I got a message from an moderator that some of my comments were flagged. I think it would be a good idea to post a message in the user's inbox when a comment or answer gets flagged. You can then edit or delete the offending post.
With regards to the feature request of seeing when you are flagged.
Most often the reason someone writes an offensive comment is because they have been angry/emotions have become heated. Being told "someone" thought you were offensive in the middle of a heated debate is rarely going to help. The best case here is that a third part steps in. Rarely are offensive flags acted on and quite often the flag is not "offensive" but a detailed request from a user.
I do not agree with you seeing, just that if a moderator warns you they should probably take the time to give you examples.
Normal case is to let you know a few examples. I have not yet had a chance to collect them due to issues related to sock puppetting and election.
Please forgive me for the delay in getting this information back to you. I can explain why in more detail in a private chat as a public setting is not the place. If you just give me a bit more time I expect to find examples although going through deleted comments takes a really long time.
Chat is the easiest for me. Sorry, the load is high here which is why the original message did not include this information.
