Persistent Filters and Blacklists

On tumblr, one of the main things people install xKit for is blacklisting. They want to be able to filter out tags that they know they don't want to see. *(As an aside, if someone is building a browser extension to fix your site's faults, you should probably take that as a bad sign. xKit has put together a rapid response team to deal with site inadequacies and "updates" no one wants.)

The way filtering is setup on imzy communities is already a step ahead, because the tags are predefined. You don't need to come up with the 10 variations people might choose to use and bloack all of them. But to be really useful, it needs to go a step farther into a functional blacklisting feature.

Right now the filtering is only positive. Yes, This. That's cumbersome for exclusion, so there would need to be Not That, as well.

But additionally, that setting should be sticky for viewing the community AND affect the feed. If the point is that I never want to see X content, then the blacklisting has to extend to what shows up in my feed, given that that's the main way I'm probably viewing new posts. And it needs to persist between viewing sessions, until I go and change the blacklist myself.
