I imagine I am not the only one that was not sure what to do in this case. I thought if they did not take it down that DT would take care of it but no sign left of my images on the site.

i don't get it.
with part of RF licence you don't understand ?

They are purchasing a license and the usage limits are defined on the various sites.  

fine, but are we sure the buyers are aware of this ?

for instance about pornography use, i had no idea about it.
RF is universally sold as "do what you want with it".

ROFLMAO!

So after accusing others of not reading or being able to understand the license terms, it turns out that it is you, Sergey, who actually didn't bother to read or understand them?!...

Priceless.
