I think we need to start labeling our pictures that we post on the CPF. Put a security tag across the picture saying where or who the picture belongs to. It might hinder the picture a little, but we can't have people using our picutures on eBay.
Another forum i am on actually has had this type of problem before. They would post pictures of a cellphone that they just bought, and someone obviously snagged the photo from the forum and used it on eBay to sell a fraud.
Anyway, luckily the person who snagged the picture to use on ebay, only copied the link to the picture and not the picture itself. So what the owner of the picture did was change the image link to link to an obscene, pornographic picuture. So when people clicked on the eBay item, pornographic pictures showed in the place where the original pictures were. Funny huh?!
