I unfortunately have had such encounters before.
There was one time not too long ago when we were in an rp where someone really did not get along with us, but we tried to ignore them. We were chatting in the oc and started a clearly friendly debate about about our characters, and out of nowhere this person says: ' I don't know why your being a troll, (username) but please don't pull this bs.' Keep in mind that they weren't even the co-gm, and he accused us and many others of other things, telling people to shut up or gtfo. We kinda left, but the gm brought us back. The rp flopped anyway.
Anyway, sillyness is welcome here. Bow down to the Silly god!
