Again, OP isn't selling things directly to end-users, so I don't know how the OP is meant to acquire the end user's consent, informed or not. The OP is exposing abilities in a tool which enables his end users to turn around and deliver something to their end users. My question is how culpable OP is for abuse of his tool's abilities, and what level he must go thru to put abuse protections in place to be not morally culpable for his end user's treatment of their end user's, and your answer is "OP needs to get informed consent". Ridiculously simplified.
