A post like this is not enough for any accusation. No proof, no details, the post is invalid as an accusation.
Until a time the poster comes back with more details, this post can be considered as an invalid accusation and a troll. Don't feed the troll until more details provided, and if the poster just disappear after this post, it will turn to be a likely non sense and invalid attack against BetFurry.
Don't feed the troll.
This is what I thought after looking at his posts. You can see when his account was created and he made such a false and misleading post today. He is not encouraging trolls to comment here; he cannot leave without saying something. If there were a problem, he would have explained it. If he did, he directly posted something like that.
