Comrades, on a recent mutual aid comm post, I received 8 upbears on my bump comment and zero other bump comments. This is a ROOKIE MISTAKE! Don't just give me heckin comment upvoterinos, BUMP IT YOURSELF! The more people that see mutual aid comm posts, the more mutual aid happens. You don't necessarily need money to contribute in this regard.
Comment mutual aid poats to bump for active sort. Also upvote the post, which helps it show up on Hot.
Sometimes I donate, sometimes I bump, sometimes I bump and donate. I usually do at least one of the two for individual requests. And I try to upvote every bump, to help provide a small social incentive for bumping.
Edit: what I should really do is get to work on bringing back the old active sort (I'm pretty sure I know what to do, just gotta actually do it). I recall it being easier to get posts to the top of active back then.
