Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
At any rate, you probably shared IPs with the person in question (therefore, sharing the same punishment). leading to the ban message. That's my absolute best interpretation from what you're giving so far.
Biganalsex is a repeat spammer on the YouTube channel, and was globally banned (not roombanned). Are you using a public IP (like at a school) or a proxy?
