This is where the lazy come to ask other people to do their work for them. I can only speculate on the user base, but here are my best guesses:
If it's any indication of how my mind works, I thought people were interested in knowing the name of the porn actress for sexual/emotional reasons. Like you have to know that Mercedes or whatever is the one you're getting off to otherwise you just can't complete the act or whatever. It took me a bit of time to understand that people want to know the name of a porn actress to find more porn of her…
I guess that's just now how I view porn. I mean, why bother with knowing the name of any actress? Isn't part of the excitement in finding something new almost every time you venture out looking for porn? I guess it's not for some people. To each their own…
