He is indeed multi-accounting and I was just simply waiting for an explanation but since he didn't provide a valid one, I did a bit of investigation.
I went to the other community and pasted his STEAM ID in the search bar. While doing that, I managed to get on an admin application created by a guy named Ayman which basically means that Zombie;Hunter = Ayman. After that, I went to Rain's account (the fake one) and I checked his email and the email contained the name "Ayman Baara" which is a reason enough to confirm that Zombie;Hunter = Rain = Ayman. Let's not forget that the IPs are exactly the same and that the screenshots provided by Bess could also prove the validity of this accusation.
Therefore, Zombie;Hunter will get moderated since he failed to respect the warning that was issued on him and took the decision to break an other rule and the account under the name of Rain will get muted until a high staff member takes the decision to ban it or to remove it from the forum.
This goes to denied for obvious reasons.
