I gotta admit that there's a lot of memes there lately that fail to make a good statement, but are rather just personal attacks, and those that do make an actual statement often get into a flame war (mostly by people missing the point or feeling personally attacked trying to distract from the point). And perhaps creating a new account to bypass a ban is for a stream where things can get out of hands so easily is way too easy. Not sure if 50,000 points is a bit 'too high' though.
The point with politics these days is that people don't feel heard or taken seriously (if that is true or not is often not really a point, lately), and if people feel like they may not say their thing, we got another one coming. Also I deem it highly possible that political trolls will then move to other streams, and then we got a bigger problem, I'm afraid :-/
