Umm, eBay has tons of adult material listed. The problem is if it's actually classed as adult it goes on a portion of the site that is only accesible for those who've entered credit card info. Now, lots of non-nude stuff from adult stars gets sold on the normal site so, so long as the ad doesn't have any images of nudity, she'd probbly be allright. However, since most people entering SaRenna into a search string ar probably looking on he adult portion of the site, general listing stuff won't come up in the search.
My personal opinion on doing the auction here is that, while it would be nice, it probably wouldn't be the best for Ms. Lee. I say that for two reasons. The first is that the burden of trust needs to be on the consumer, not SaRenna Lee. By this, I mean that we know that we can trust HER, both because she's got an excellent track record and also because it would be bad business for her to stiff a customer. However, on an open forum like this she has no safeguards. Anyone can log on, bid, and then disappear into the ether. eBay at least provides some methods where she can take some action if some lowlife tries to leave her hanging, especially if she goes the PayPal route. I don't think that any of the regulars would screw her like that, but then does that mean that the auctions would be limited to long-term people? Heck, I know that I'm a sweet guy, have been a fan since the 1993 issue of Cheri, and wouldn't dream of leaving her holding the bag. However, none of you know that for sure, nor does she.
Beyond that, if she want to get the best return, she gets a heck of a lot more exposure on eBay than she would here. More exposure, more potential bidders, higher selling price. Heck, she posts here that something is up for auction, we'll all be over there in a heartbeat, she gains nothing by putting the auction here.
Now, all of that said, if she wants to do this as a way to outreach to her fans, then having an auction here or on her website (which I'm sincerely hoping that she reopens, having lost all of my saved files from sweetsamples in a computer crash) would work. Do it for members only and you limit it to the more dediated fans. Of course, if she wants to outreach to fans, she could just send us all something. I'd like the green scarf from her Score pictorial, please (it's my favorite photoset of her ever, tied with the teacher one). . .
Seriously, I think eBay or another online auction site would probably be the safest way to go, for her.
