I have to wonder what is it about you that makes them ask you to do this...
I used to hunt down links for my friends because they're incredibly technophobic ("Using google gives you viruses, FOX news said so."). Then they wouldn't book mark them ("Bookmark? What the hell is that?"), and I'd keep having to hunt them down again. So I made a yahoo group to have a sort of links catalogue and basically told them : "Here. Everything I find will eventually be posted in lists by category here."
Then yahoo deleted it because someone complained about my not allowing people in (it was a friends only thing).
So I remade it and was convinced by the guys to open it to the public. And then I started getting flooded by requests for free porn. Which pissed off some of the regulars who were antiporn, and got the group deleted.
So I remade it again, and made an adult group as a companion and said "Put your booby requests here and leave my regular group alone". Since then it's done well. Except I have this rep for being able to find weird stuff because I take occasional requests, and sometimes succeed.
I will have to say that anything transgender/bdsm/fat chick related is mind numbingly popular. The amount of people I get privately requesting naked fat women, women who were formerly men, or women who like to beat men is staggering. On the other hand if you like that sort of thing I will eventually have the finest compiled list of it on the internet. Along with God only knows what else...
