However, if that user deserve a "block", he must be in a vote, which can decide that he'll be ban or not.

(The minimum required must be about 75% contributors of that project and any user can add another user to the vote. But, if anyone want to vote or add someone to the vote-list, they must have at least: a proof, a reason to ban and a suggestion for the user in the ban-list. If that user don't change his/her behavior for about 2 - 3 weeks, he can't contribute for that project more.)

p/s: I want to suggest a little feature here: all contributors in a project can vote any user to be an leader of that project.

What do you think? I'm sorry for a long and boring feedback, but hope that you guys at POEditor will read it all! Thanks!
