Was this a joke?
Almost all of the posts are from the OP. The default for forum conduct seems to me to be that the OP has a certain amount of free reign in determining what sort of content he/she wants to emphasize in his/her thread, so long as the content follows the TOS, and stays on topic to the forum. Photos of kissing or holding hands both generally are within the bounds allowed by the TOS.
FSUnole2k9 mentioned about halfway through the thread that he was shifting to a broader theme of gay passion. Especially as the OP I think he is allowed to do that.
If you wanted the content to shift back to men kissing, you could have suggested it considerably more politely.
