Hey, never let someone intimidate you by promising to report you. All the report does is pull a Staff Moderator's attention to your chat log, nothing else. The Mod on duty will check through your chat log to see if you've said anything that goes against the rules (like swearing or harassing), and if he/she doesn't find anything, he/she will dismiss the report. That's all that happens! In fact, reporting people for no reason can lead to consequences itself. I'd say you reporting that player would be a valid case, right there!
