What I've concluded is that:
Warran, your friend, downloaded a spambot.
You both got banned for it because of similar IPs.
We figured out it was Warran and not you, so we unbanned you.
Then, you asked if your "other friend" could play (which was actually warran)
We said yeah, if you invite warran to prove your friend wasn't him
So you joined on another PC pretending to be warran so your "other friend" (warran) could play at the same time
Is this true?
