It's a forum for posting pics of celebrities. The people who post content here don't get paid to do so, unlike the paparazzi/photographers who take them. They're doing so as a "favor" to the forum community. As long as they aren't breaking the rules of the forum, which Kaos isn't, then why attack him for providing content to the community? Not only is Kaos not breaking the rules, but bashing on him for posting content IS actually against the rules... There's just no reason to be rude about it. Being rude for rudeness sake doesn't make someone look cool, it just makes them look petty (and is, again, against the forum rules). Being inaccurate in that rudeness just compounds the issue by just making them look foolish while they do it.
Now personally, I don't care either way about Kaos' posts. Some visiting the forum might appreciate them. Others, like yourself apparently, might not and that's perfectly fine. If you've determined you don't care for what Kaos generally posts, use the ignore option on him. That's what it's there for. If you (or others) would like the forum itself to change it's content rules, then please feel free to start up a discussion in the Site and Forum board about it. That's what that's there for.
At this point though, I'm going to be publicly done with this topic so as to not take up anymore board space. If you or anyone else would like to respond, feel free to PM me.
