The LJ board will hear about this!
Thank you to the anon on wank_report for this one (I’ve used much of your original wording in this post).

A while back, Linda92595 participated in a fic exchange at the SPN comm deancastiel and was very vocal in her dislike for the fic she received.

She was asked to consider locking the post but didn’t because a completely different community mocked one of her manips.
She was subsequently barred from participation in future exchanges and accused the comm mods of spamming her journal with bots.

She attempted to sign up for the current fic exchange, which led to a confrontation on her lj with one of the deancastiel mods (deleted, but screencapped).

And to round it all off, the Spnpermanon thread on the subject.
