Maybe I should make a public shame list in meta for all of the useless spam posters. Add the shit posters to it and point campaign managers and staff at it.
You would probably be faced with a lot of hate (mainly by the people you add). But I would support creating the list.
What about some kind of public voting thing for the quality of users' posts? Not sure how that would work.
Well, we would need to make sure only obvious spammers were added. Not sure the best method for adding users, but feel free to make suggestions.
Well, it would be tricky you would need to check on the crap posters now and then to see if it was just the odd crap post.
That said Ignore is a button that's been around for a reason although it was more convenient when it was color coded since that was an easier way to tell.
