Uhm, you didn't invent a time machine by any chance? Sounds like you came here from more than two and a halve years ago, I haven't heard the word "tplink01" since back then
The mod you are talking about has never been public, and for sure it wasn't tplink's. He also did not have the original KoG mod from 2011-ish, it was just another mod of that mod (known as KoG 2.0) that some more people had gotten hand on. Be told your money is gone, having given it to this guy. I know he was taking an aweful lot of money (like 20€ for some vip shif iirc), but you've spent that money on him solely, not on having perks on the KoG mod for all eternity. Many of the things that you could buy on his servers were put into the mod by himself (or rather the guys helping him, considering his limited skills), so they simply don't exist in other versions ('flavours'?) of it.
The only thing I don't understand in your text is "Since the DDnet has" - do you mean they are hosting it? I don't think I've ever seen them do that, so what could you mean by that...?
Furthermore, how are you planning on 'restoring old accounts' if you don't have any connection to tplink, which I assume you don't because elsewise you'd not be askin for the mod here.
Anyhow, if you just want to play the mod nowadays, there are the 626 servers hosting both the original and the KoG 2.0 mod; Build and level servers. Unfortunately but somewhat understandably there are no accounts from the time tplink was hosting it, nor from the really old days when it still used to be nlvl's response. Apart from that, almost noone is playing KoG|LvL anymore, you must be lucky to get even a handful of people to play with
PS: Would you mind telling me how to timemachine? I'd really like to live the old days of teeworlds just once more....
