Mind you, it wasn't at the SRB2MB. Simply, it was some dude who had an avatar that flashed rainbow colors at an incredible speed, and Sykotic (or Chiisu, or whatever the hell that bastard calls himself nowadays) claims he had a sister with epilepsy. Because of this, his sister could accidentally see the board and have a seizure. To me, it sounds like total bull**** (his little sister seeing the forum he was browsing, suuure, and to see that one avatar out of a sea of many, many others). Either way, his sister supposedly had a seizure and almost died, but then he saved her with some medication or whatever.
To summarize it all up, internet drama (albeit most likely fake to have something to talk about fgsfds). Of course, the internets are them serious businesses... Also, it went from a graphic replacement mod to talking about some person's sister reacting to an avatar. o.o
lol, internet
