Reminder that too many open / pending flags in a topic will automatically institute a timed close on that topic for 4 hours. It won’t re-open until the flags are cleared.
What I view as a big problem is ..
- personal attacks, which should always be flagged and removed under penalty of possible suspension
- excessive replies
.. we don’t do much for the latter (except for new users who are limited in how often they can reply anyway) but we probably should. Even for established users. 
We do have the “did you know you have replied to this person a bunch of times” just in time reminder but it has no teeth and probably needs 'em to be effective
