We should create a bot service that would flag any post or comment flagged by spaminator or sadkitten. Rather than delegate sp you could assign it one vote per day or more if you wanted which would only be used if needed as a downvote to erase any gains from the spam posts.
So it would be like the curation trails that currently exist only for downvoting instead of upvoting.
A spaminator-trail, not a bad idea.
