User blog comment:Collisions/Demoting an owner/@comment-24545405-20151018142834

I believe a "community consensus" would require most of the users on there to agree with the poll. However, I would advice against a poll this time, and instead just have users say whether or not they want the owner demoted, since the owner (or anyone else) can just make as many alts as he wants and sway the poll in his favor.

If you're worried the owner will get malicious and start banning people or trying to delete things to avoid possible demotion, I believe a VSTF or staff member will help in that case. They will likely prevent the owner from removing and banning people (though not permanently demote him), and the voting can go on undisturbed.
