It just needs a better barrier preventing the spam posts. The "picture puzzles" dont always appear when starting a new subject or post, so they are not very effective. To be fair it isnt as much spam as before. As long as nothing X-rated pops up again, that was a big no-no.
A moderator is not needed here. Its a very good, well mannered forum. Even when we may not all agree with something. Generally its treated like an adult discussion with sensible debate and humour.
I very much doubt most people who post here would want this site turning into Hats forum, where even the tiniest little hint of dissent is removed.
