Jumping off ledges/ladders/into kill zones, repeatedly downing themselves, rushing, etc: Trolling/griefing
Constantly falling prey to spit, lagging behind, getting mobbed, ending a surv round with 30+ points: We've all been there
I've rarely seen situations where there has been legitimate trolling and that person wasn't dealt with by an admin. The few times I've noticed it, I made the call out over chat, and started a !votekick if necessary.
That's it. That's the plan. That's community. Work together - admins included. There doesn't need to be a complicated, drawn out, "members get more power" plan here because we're all enabled to do the right thing and make the call outs. If you're frustrated with how it's currently being dealt with, talk to an admin. If you want to take a hands on approach with it, apply for admin.
In my opinion, if you have any other perceived issue and you've not tried talking it out, you can vote with your presence.
