Long post ahead!
Everything following has been personally witnessed and acknowledged by the mentioned people.
Disclaimer
It is possible the Illuminati staff, vali in particular, is not the culprit of this recent case of serial blocker server attacks, and that these were not made in the interest of the Illuminati server.
However, so far, all leads to believe otherwise. The concerned party were not keen on clearing themselves up, instead acting as if they were trying to cover-up their implication in the events.
The people responsible, whoever they are, must be soon identified and protected against, so that other servers can run as alternatives to this abusive Illuminati server.
The key players
vali, an exec clan (clantag "exec|L") leader, a player who used to be a troll wb at times in v3, thanks to the help of Contra, the "wb king" (he can often rule the race 5 minutes after connecting), DDoS xRoThx's blocker servers, and many others, to establish his own, nicknammed Illuminati (ironically), which was adverised as "DDoS-protected" (you don't say!).
Afterwards, for an unknown reason, Contra was betrayed by vali, kicked from their project and even banned for life each time he connects on their server.
To this day, without Contra's help, vali still manages to down other blocker servers who pop up once in awhile, soon after they start.
NiKiS mentionned Teemo as responsible. It's true he is part of the exec clan.
However, I think Teemo is amongst the most decent of their members I know of.
He told me he disagreed with his clan's practices (when I mentionned DDoS and cheating on their own server).
I saw either Vali or Tinlex say that Teemo undid a ban they performed on a player, which they would redo indefinitely in response.
However, it doesn't seem Teemo was banned from the server and revoked his admin rights, which happen to some admins who have conflicts with vali. It is a surprising element, so he must hold some importance.
Why should you care?
Do you want to let a bunch of abusers control everything?
At a whim, they can act as they want. Would you give all power to the guy who wayblocks all the time? Because that's what you do right now.
You can't host your own blocker server because of them.
If you want to host a server with a better ping for you country, forget it, at least while they are around!
You are a mapper.
You can't play with other people if you want to load another map, any map. They won't allow it.
We are stuck with the old blmapV3Royale, or whatever choice they make.
xRoThx at least had an outmap in it, where you could enter into the wall through the hole next to the ninja at the race end. He made blmapV3Royale2 with more sections. Other people made variations with different features.
You can't fight them because you risk being hard cheated against.
You can't badmouth them, because you will get at least a mute and up to a life ban.
If they hate you enough, they will ban you each time they see your name even if you change your IP to avoid the life ban.
Do you want to let them control even more of Teeworlds in the future, and possibly introduce monetising systems for getting upgrades, bribes, and such? At this point, it seems far-fetched, but if they are a little more than script-kiddies, they could do this and not just get the top spot for glory and perpetual win.
How the Illuminati server is run
This Illuminati server belongs to the exec clan.
Teemo below told the server was his in particular.
The name is written on the last line of background credits at the start of the map.
When you log onto the server, it sends the chat message "Welcome to {exec_member}'s server!", where {exec_member} is each time a different member from the exec clan.
vali and Teemo are the clan leaders.
In the start list, I also saw Menavodi, avocado. According to someone who knows these, it seems they are actually not exec, but vali wanted to make people believe it. Also, I talked to Menavodi, and he seemed uninformed of all this.
Confirmed admins include Tinlex. Previous admins who were retrieved this status include: Contra, Marcella, Lickout.
vali throws many admins status at his friends and people he wants to please, but also retrieves them expeditiously, in the way he cheats in the game. Admin granting is just another of his toys.
Many people seem to try to please vali to get an admin status. I heard this of Tinlex and Marcella.
Those who lose it often get banned, such as Contra and Lickout.
I could confirm the admins, because they were mostly cheating, using their powers for worse unfair treatment than wb.
They teleport themselves to safety, spawn with weapons. They don't cheat right away, they play, but when they lose, they use a deus ex machina.
If they get annoyed, they start casting "curses" on their opponents. They make teleport him to dangerous places, kill him, sometimes indefinitely, turn him into a spectator, or lag him hard (it is probably not DDoSing, but limiting the ping from the server).
They do so when themselves attacked, or when taking sides with their friends.
They are just regular nasty blockers, which most blmaps are infested with, script-kiddies, admins.
Sometimes, vali alters the "physical" rules of the server. It makes for fun gameplay. o_tee_one, admin from r0x.fr did such events before. However, vali, unlike o_tee_one, disregards what players want: o_tee_one would only do it when the number of players was few, and would care not to disturb players with his "weather changes".
Still not convinced?
There is no denying that new blocker servers, and existing Royale blocker servers get attacked. Just try setting up a Royale server and have 10 people play on it for awhile. It won't take more than a few days to get your server DDoS.
However, the Illuminati server, who takes the top spot, doesn't get down. For regular players, it doesn't seem to suffer from frequent attacks either. This alone is suspicious. Maybe they just have better host and better protections overall?
This is what vali said. However, he refuses to testify here on this post, which could attempt to innocent him.
More generally, he tries to avoid the subject. He discards it as "just kiddies saying what they want", pretends to laugh it off and ignore it, as if it was obviously ludicrous.
However, as much as he pretends not to care about it, he acts as if he is wary on it. Just try to talk about it! You will immediately be muted or banned for life!
Finally, you can try to talk to the concerned people, which will verify what is being said here. You don't have to accuse, it is just an investigation, you shouldn't be banned depending on how you ask for it.
What to do?
As this topic asked for, the Illuminati server should be banned, even if it doesn't completely solve the problem.
People should be informed. Below is how I proceed.
vali has succeeded so far, as the Illuminati is the only Royale server running, and the most popular one. If you try to join another server, it will be DDoS as soon as it gets a little attention.
Boycott the server by yourself will be hard, since there are no real alternatives for now, and few people will follow you.
Therefore, start by spreading the truth in vali's Illuminati server!
If you go directly against vali, you will quickly be banned for life. If that happens, you can still avoid it by changing your IP, which only requires restarting your router.
You can give people this link: http://qr.net/vali which redirects to this topic.
Its short form allows to share easily in the chat and type it by memory into the browser, which is required, since most clients have no copy/paste function.
It works better if you give it by private message, since it will be more discreet.
Suggest others you inform to do the same with others.
If they hesitate, because such a link could redirect to anything, give precise directions. Tell them to go on the official Teeworlds forum, to find the user NiKiS, to visit his topics (he has few), and pick the one about the server.
When enough people are ready, a "revolution" can take place. vali cannot ban everyone in his server who badmouths him, because he would act against his server, by making it much less popular and infamous.
Catch16 is the best mod! It is not zCatch, but its ancestor, only the original is better.
