I think they would be insanely stupid if they did, seeing the amount of traffic the altcoin section gets. They should just get some more devs/mods, and expand the altcoin section with more subfora. What they are doing now is probably caused because they did not see this coming, are struggling to manage things with the team they have, and they lack a plan of how they want to move forward. I bet that if they could find a way to monetize this forum better (I think the ads they have now are marginal amounts), they would not mind us being very active.
Anyway, if they do ban altcoins, there will be very little reason for me, and I guess for many other as well, to keep coming here. Apart from maybe once in a while.
the forum has a few mill USD in donations they are not short on money they are having new dedicated forum software made so my guess is there cleaning up everything before that's complete I have no idea if this new forum will even alow altcoins
