I only pointed out that there Terms & Conditions read like this:
“You must not upload any images containing material that is of an adult nature, illegal, defamatory, promotes racism, hatred or discrimination.

Any images found to break our terms and conditions will be removed with no warning. Anyone who uploads an image that violates our terms may be banned from using this site with no prior notice.”

Now, if you have had great luck, that's all that matters I guess. Just don't be surprised if one day you get those ugly boxes in forums that you pasted a url-pic in that says VIOLATION. lol

As an aside, here is another site one might look into:  http://www.imagebam.com/

Their Terms & Conditions on the hand have no such written restrictions, and in fact state all users must be 18 yrs or older. Yea right. Just an alternative anyway.
