In room 10 of Stack Overflow we have had a troll (or multiple trolls) for the past few weeks casting random flags and generally being disruptive.
Today for example I woke up to this.
For us or room owners there's no way to handle this kind of disruptive behaviour, and moderators cannot help either, given that they can't be online all the time (as it appears to be the case today).
Also warnings don't seem to work very well.
What should we do?
On a side note I see that we also have a similar problem with stars (image by @Mr. kbok).
