It could be tough to find a buyer.
The commercial value of a forum lies in the number of members it has. In turn, the number of members it has depends on the size of its "critical mass" - the very active, prolific members who write enough and regularly to make the forum lively and interesting, attracting the readers to keep coming back.
This forum just lost a significant number of its own active, prolific members, through Steve's bannings. And this forum also alienated a big proportion of its remaining readers, through those same bannings.
Now, if you were a prospective buyer, wouldn't you hesitate?
