If he does it again, or someone does this to you, simply ask them *nicely* to leave you alone. Then ignore them, and make a note somewhere of the incident.

If they try to get around your ignore, or continue to harrass you, file a report. Make a note that it's ongoing harrassment, and give them the date, time, and channel.

Too many people think they have a right to force others to listen to their opinion, and cross the line. If it's a one time thing, let it go. You know you are within TOS, so why worry?

If there's a second time, add a possible step up the penalty volcano for them. Who knows, your report could be the last strike, that gets them banned.

Just keep yourself out of trouble, never answer them, swear at them, or act like you're afraid. That's what they want. Bullies hate people who are'nt afraid of them, or people who don't care.
