we don't have enough proof to say he's an alt but it's still possible. the only thing he can do is lay low while this gets sorted out. i don't think he's an alt but i don't like the coincidence so i'm being weary.
Maybe you should law low so you can leak out some of the stupidity lurking in that mindset.
The one thing he should do is contribute to the community and eventually earn our trust as not being an alt.
Or, he is an alt, and he will eventually make a "here's who I really am" topic, pleading for forgiveness, but which will only result in the iron fist of the forums pummeling him into submission.
