I don't have any knowledge of it myself Crystalrose and haven't seen or noticed it in posts but I don't get to them all I'm afraid. The one thing is though if people are being rude to your posts then try to let it bounce off. It's easier said than done I know but sometimes people interpret things different from how it's intended or have their own issues to deal with and may not even mean to be rude. I know in the small amount of chat I've been in that it's easy to get lost when a whole group is there, especially when you send a whisper.

Try not to let it bother you too much and if it's blatant and really not nice let a mod know so they can deal with the person.

I wish you the best.
