If the campaign was to get him banned, then yeah it failed. But I don't think anyone really expected that to happen considering Twitch's CEO and moderation team are all dick suckers of his.
It succeeded spectacularly in making Twitch even less profitable than it already was by chasing out the advertisers and getting Hasan on quite a few Twitch streamers shit lists or, at the very least, getting them to drop the walls they put up around him a little. Not to mention that he has clearly been instructed to tone it the fuck down and has to now stream with a gag in his stupid mouth.
Everyone involved is a faggot, so I am happy that everyone involved got hurt by this.
