The CEO of proboard clearly admitted he didn't own the posts we have licensed him to use them:
Further, the postings on this site are not owned by the forum admin - they have zero right to sell them to a third party.
They are owned by the person who posted the message. When a person makes a post on a ProBoards forum, they specifically license ProBoards to use that content on the ProBoards forum.
We own our own thoughts, by their own admission, and proboards would like to think they can keep them.
We are able to collectively, if he wants to be a jerk, revoke that license and en-masse delete or threaten to delete our posts which is not all that difficult and also our accounts. He won't like that at all so if we actually like the new board and the idea of meaningful and constant moderation this can be done. Things can be done. I am not a lawyer but I do make sure none are never needed at work
