I think that's a fair point and I wonder how will this effect the freedom of expression on the internet. If you can't find the distributor then it'll be really tough to get a handle of this.
On the other hand the sheer over abundance could simply break the entire value of revenge porn as in "nothing is real anyway so it doesn't matter" sort of thing which I hope would be the case. No one will be watching revenge porn cause they generate any porn they want in a heartbeat. Thats the ideal scenario anyway.
