I have only just become aware of flagging comments. Some of the threads tho' you would need to flag 100 and a lot of bad feeling is generated. Best nip it in the bud early I reckon.m
The threads that you are flagging are the ones that need to happen.
I can see why you would flag a whole thread, but I don't think that will ultimately get us anywhere. If you care about the accessibility of this site, then I implore you to upvote those threads^ and flag the bad comments within.
