Some peoples' parents are just stricter than others. Even though this is the age of technology, there are still a lot of people who look at things like the internet with skepticism. They aren't familiar with it or have only had bad experiences with it, and to make sure their child is safe they will put limitations on it. My parents were only restrictive of forums and instant messaging. Otherwise, as long as I didn't give out personal information, they let me do pretty much whatever I wanted. According to Schmooky's profile, he's only 11, and while he seems able to hold himself well on forums, his parents still might not be comfortable with letting him go around talking to strangers that are probably significantly older than him.
Since it's his older brother that posted, though, I feel like it could either be a really controlling sibling or the parents asked him to do something about it because they're busy. There's numerous scenarios this could be. Regardless, if Schmooky likes Rayman so much and enjoyed his stay on the forum up until now, it's likely he'll be back in the future and maybe will explain what was actually going on.
I would like him to stay since he never has given trouble to the community, he's actually polite with all.
