What behaviour deserves a block on here?

Paid shills for sure. Now I'm blocking other accounts that associate wIth the shill accounts. You don't want professional trolls on someones payroll having access to your account or content. These people have a serious bag of tricks to screw with you. Mass reporting, hacking devices. Arguing constantly but they don't even believe in the things they're arguing with you about. It's just to waste your time and keep you from engaging with actual users as a way to shut you up. I've got a pretty good block list. I can tell they're professional shills by the magazine like content they produce. Cut and paste talking points, every single post attacking Trump, nothing else. Even real Trump haters aren't that obssessed.
