It's possible with several caveats.
There are modifications that will force users to read popups based on what (I THINK, so don't hold this in concrete) Forum they are in so we would have to put the Daddy/Girl thread in a forum by itself in order to do that (and that's provided that we can find a modification that will work with the version of software that we are running).
I will look into it but also will encourage people to use their judgment when posting photos. Just because there is not a neon sign above a thread flashing rows and rows of "rules" does not mean that there is not some responsibility on the poster to pause and ask themselves if what they are about to post is a good idea or if it might have ramifications to the other members or site owners.
Hell, we have folks who have been a member of this site for over a year who have never read the TOS.
