incapable of handling such things without some kind of public showdown that involves social media. But there isn't any formal power structure. The only things "communities" can base decisions on are legal records and social reputation. If you don't want to be at a conference where someone can be abusive to others, what exactly do you suggest they use to determine who can and can't get in? An extralegal quasi-judicial system that weighs rumors and conjecture to keep undesirables out? And how do you keep that process meaningfully distinct from a conference where a bunch of people pile onto someone for whatever reason to ruin a reputation? tl;dr: It's not possible to have it both ways.
