On my DVD media posts it seems that I had links to the adult sites in my posts. My image hosting site claimed to be a family oriented site and do not contain nor allow adult related materials.
I have no idea where these links came from and I apologize for this.
I saw those links at the time–it seems to be a skeevy site that automatically appends an advertising link to the end of any photo link. By leaving no space between the two links, they hope that the poster doesn’t notice. You could defeat that by copying the URL directly from the address bar, or editing out the extra link as you post. (Or pick a different image hosting site.)
