I'm suspicious. They way he said "Hey, I'm new here." The way he posted
and then contradicted himself by trying to post the link to ROBLOX. It seemed like he knew it was blocked. The way he knows that there a lot of idiots who are new that go
"LOLZS HAI GUIS IM NEAW AN I LEIK PI!!! "
or something like that. His sig.
All of this adds up. I think he might be an alt.
But on the off chance that you aren't an alt. Enjoy your stay.
