Since I'm not Council, I'll throw in my opinion here.
I think the accounts for Experiment, Stegy, Dalll, Jeff, and Claws should all be banned but I doubt Experiment and Stegy are the same person as the last three.
Even though Experiment, Cysid, and Stegy are all the same people, I'm pondering over whether Cysid2 should be banned. Experiment is racist (Already banned FateGas for this), and Stegy is just a copy of another account and there isn't any point in letting it post so those you should be gone in my opinion. Cysid however seems to manage to keep control of himself on his main account.
You know what, all accounts should be banned. If he is going to act like that on one account, I'm sure his actions will just transfer over to the other one. Not to mention he has sent me death threats in the past with his excuse being "I was bored and meant to send it to Ugilick."
Of course, he has already shown he is fond of making new accounts so I doubt banning would even have any effect at all. Even if he decided not to make a new account, he seems to know his brother's password (Or Betaband seriously needs to learn to log the fuck out once in a while) so he could always use his account.
Actually, that's another point for banning since I happen to recall him unpublishing all of his brother's storygames which is a huge dick move in my opinion.
TLDR, ban them all.
