I believe what has to be noted is that there is really two (maybe three) types of ERPs.
Firstly you will have the erotica, or literotica cause that's a cool word...
On a slightly more serious note, I think people should keep it private in most situations...
On second thought @Lady Amalthea pretty much summed up my own thoughts regarding the matter.

I don't know about you guys but this always made me think 'yeah you're just trynna have a quick wank/shlick before bed and just want me to write some good shit for you while you do the bare minimum to keep me writing'.

And then this is what happens when two of those 'I only wanna JACK/SHLICK MY ASS OFF and not WRITE' people meet and agree to roleplay...
The question is, how does one advertise that as a highly literate chap/chapette, not only do we desire to shlick, we also desire to create a literary work of art? ... and now I kinda wanna try making a copypasta on the subtle intricacies of ERP lol.
