Please explain what you are talking about. My students did not spam a community tag. As far as I know, NONE of my students used an "SBI" tag.

And, since when did HiveWatchers assume the role of policing community tags. If a post is SPAM, then deal with it appropriately, but if it is simply a post that is unwelcome to a given community, let the community admins mute that post or that account.

This is ABSOLUTELY CRAZY that you've done this!
