While I was opposing BSV flags, I saw many other inactive flags which are probably wrong, which occurred in my absence. I say probably wrong because they are against people Id be more or less inclined to trust, and/or were opposed by people I trust.
I wouldn't try to vote on all possible Flags. There's far too many of them, and ideally many different users should all check a few Flags once in a while to make voting more distributed.
You can semi-automate it, then it's much faster than the time it takes them to make them which is important. Were it the reverse, we'd have quite a problem on ours hands.
