No.
At no point does the urge overcome me to post, "I like poo", or "I can't afford (fill in the blank)" for my time on a forum, or 90% of my messages.
I comment on things that are entertaining, interesting, or I have some thoughts or opinions on. I read more than I post regardless of the forum. That includes both adult and mainstream. The only difference is that some have stricter rules in regards to images, profanity, or subject matter you have to take into consideration.
