In recent weeks the GOS has been flooded by Telephone trolls.
The record is nearly near 750 in a day. It is hard to disambiguate between common RW trolls and the Telephone trolls. One and done works.
Don't give the trolls a break by saying something useful to them.
Yesterday elfling's bots beat them down to fewer than 150.
Edit to add:
Trolls by the pound, ounce, and notice . . .
