Of course they can leave. Not just that, everybody can leave for any reason whatsoever, including being bored of the project. But if you're leaving because of abuse, you're both letting the troll win and potentialy opening yourself to more abuse. If you're sufficiently enraged by trolls, you may overreact, and start supporting policies that are more damaging than the trolling itself, like supporting surveillance or forcing KYC on everything. Let me qualify this by saying that I support reporting people for abuse to the authorities if that's a thing where you live, but I don't support asking for more surveillance just to catch trolls. I see this pattern every day, on every level: "I'm being victimized and something needs to be done about it". I hope that people will think about what "something" is and make sure it's not making things even worse.
