I noticed that you sent a nude picture as a visitor message. This has happened after giving you a warning for the same. Considering that you just helped us by noticing a thread with lot of nudity, I am happy to give you one more chance.
Kindly note that other user is banned without warning for similar images. So, keep these type of images to private messages only. Forums, profile, visitor messages, groups etc. should be free of nudity. I hope you can take care of that issue.
