Not any more since the last wave of closing "alleged ISIS" accounts. I can't stand those religious retards either, but banning people just because they follow a religious cult of killers who spread hate and murder threats?
You could use the same argument to ban practically everything... including followers of Donald "Muslims out!!!" Trump, Frauke "Shoot refugees at the border" Petry, Recep Tayyip "Kurd Killer" Erdogan or whoever is the King of Saudi Arabia.
None of these groups are in any danger to be banned from popular social media sites despite their ideology being very similar (or, in case of Saudi Arabia, identically) to the IS and their followers equally murderish and morally depraved (Erdogan, Saudi Arabia, the neo-Nazis burning refugee camps down in Germany).
It's inconsequent and the mere possibility of banning someone over anything that members of another (whiter? religious-er?) group are allowed to do opens up highly complex moral issues.
