Your fine, some idiot saying "oooh ima report you!!!!!" shouldn't worry you too much. I know I've been reported before and I'm fine, no banned accounts ever.
Some advice for the next week or 2. (you should be fine, but if you care about the account)
Don't bot on the same character for more than 5 -7 hours.
Change zones every so often.
If you can do a hard log (turn wow totally off) for about 5 minuets. Do this every so often.
In future, when you get called out, either ignore it (if you aren't at the computer) or make it a joke (if u are at the computer). Some thing to the effect of "oooo me love you long time if u buy gold from me. Only 100 dara per gold." always works for me.
