what happened with Samsora? Because he's still doing fine and uploading vids/streaming. As for the others like nairo cinnpie, zero, and keitaro they've all been shutdown. Zero was banned from twitch but i'm not sure why the others weren't. it's just weird out here, but people like Marss, Leo, Cosmos, Riddles, Dark Wizzy, Leffen (lol) have moved on and are still doing wifi tourneys.
Nintendo has never (regardless of all the begging and ridicule from the community) involved themselves in that scene. They probably knew this shyt was gonna go down at some point. All sakarai has to do is see all the shyt about Smash players hygiene, and look at all the death threats he his team and nintendo receives when a character they want isn't announced to know this fanbase ain't worth supporting.
