I'm a little late to the party, but an avatar doesn't count as trolling. I think boltster's old avatar was of icygamma's dad or something. There is no way a single avatar can upset you enough to be called trolling; perhaps a minor annoyance, sure, but it's definitely not trolling. Now, if she were to constantly post your picture after your posts, we might have a case then, but she isn't so we don't.
