So the meme topic was closed. According to Eljay it was closed because:
According to him, the topic is "Too spam-y", even though it is a Topic about posting memes. On the boards, there are many topics that could be labeled as spam with no real discussion yet haven't been closed. So why close only the meme topic?
Next, it was 'controversial, especially among staff'. While there was no controversy in the topic itself(aside from posts that could easily be flagged for being offensive or what have you) the controversy mods/admins might have over the topic shouldn't be enough to close it if the controversy itself, which I can only assume is opinion, is not liking the topic. That said, it is my understanding that TTV hasn't set any specific rules for the mods other than those in the FAQ. The only conclusion I can draw from this is that TTV hasn't drawn a line for what exactly IS spam. From what I've seen, it's whatever they don't like that ends up being closed. Ergo, they do whatever they want.
