This happened to blok's city RPG, exact same thing, and from what I know and seen before, the same guy has been spamming for years.
Look back in Drama, about a couple years ago, I'm pretty sure there was someone with an exact same method used, and currently only his buddies are left trolling on Bloks's City RPG, but SuperUnova did spam Blok's City RPG earlier.
The reason I don't have a chat log is because I've been moderating and playing on the server for a 5-6 hours and I'm really tired, he impersonates me and spams and I kick him over and over(Eventually he gave up, I couldn't ban because the !b feature was broken), sorry for not adding a chat log and what not, hopefully there was someone on the server that managed to get one.
someone was on the server working with SuperUnova that's why it references seath and ifrits, seath was looking at the blid and told the server that he was watching to see for any name changes, and ifrits is just a player that SuperUnova made fun of.
