I see what you mean, but he's posting in the Games section, which is intended for discussion about other games. I think this will go one of 3 ways:
1. He spreads it all over the forums and gets banned for advertising.
2. He keeps it up in topics in the games section that have nothing to do woth Roblox and gets banned for spamming.
3. He only wanted to post here once, and has run back to the Roblox community, never to post here again.
I'm hoping 3, but it's unlikely.
