The troll in question had an email account linked to him which Jessica Coen was given by Gawker media. She emailed him this message which he and the other anons are delighting in. If you read through the threads the troll in question and other anons are discussing Jessica's offer, trying to find ways to manipulate it and unsurprisingly showing great cowardice in the face of the message. They fear being led into a trap where they are somehow outed and doxed. This is textbook feeding the troll but it shows how desperate they are getting over there at Jezebel when no one is listening to their complaints.
