pepperlandgirl, I looked at the other threads you mentioned.
Adult Services
This was a thread where a poster was asking about various terms in the newspaper. This is a question that has a factual answer - which is what the Straight Dope is all about.
A Complete List of Sexual Acts (That one made threadspotting!)
This one is people making up sexual practices. I will grant that some of them are outside the bounds of good taste, but the sheer outrageousness makes them unbelievable. Also it’s in the BBQ pit which has a little more leeway than other fora.
If given the chance, would you have sex with a dwarf?
I don’t see anything as descriptive as I see in the OP in this thread. To which post are you referring?
Sex on the Brain
As far as I can tell (I didn’t read the whole thing), it’s double-entendres, again not too explicit.
The Smut Shop thread (Prism’s stories were explicit. It took Slythe WEEKS to move it to MPSIMS, and I don’t remember ever hearing a peep from you Euty)
That thread was clinically descriptive, and again I don’t remember seeing anything as explicit as in the OP here. The reason the thread was moved to MPSIMS was not because the posts contravened board guidelines, but because there was no debate or opinions being asked.
Love Letters from Cheffie
Haven’t read that one.
Satan’s Ass (It’s closed now, but it too make thread spotting!)
That again was more of a “debate” or an “asking your opinion” thread, which in my mind is appropriate to the SDMB.
Compare a post in any of those threads to the following lines from the original post in this thread: the paragraph starting with “Holly’s hand began to rub higher along Amy’s thighs…”
I’ve read many posts in my day at the SDMB, and in my opinion this thread is in a different vein than all the others you’ve mentioned. It is deliberately meant to arouse the reader. None of the other threads you mention had that purpose. One could argue that because it is erotic it doesn’t deserve to be censured, but the problem is, if this thread is allowed to go without comment, at what point will a comment be justified? For better or for worse, the USA is a society in which pornography is deemed not appropriate for all audiences, and something that the government is justified in censoring.
