I've used it once or twice as a bidder. It seems alright.

ah okay im reading th FAQ they have im thinkin of moving my adoptables and auctions there for ease of access to all people as i have audiences from twitter / tumblr who don't have FA accounts to bid.

I have used it like.. 3 times now. I prefer FA. if you get overbidden, you don't get any info if the guy overbidding you removed his bid so in the end, you still pay even if you already redistributed your funds. There's a bug on the site where you can't change your email adress. I made a bug report quite a while ago, over a month I think, it was still not even aknowledged by anyone there, doesn't fill me with confidence. I'm not sure but I think I got no message when I was overbid.
Feature wise, there are so many painfully obvious features missing. For example, looking for an SFW YCH? well though shit. Either you go into your setting and deactivate all NSFW posts permanently or you see all of them, there's no way to filter. Also not for anything else. Youd think a function like "lemme filter for themes/genders/etc I search an YCH for" would be one of the first features put on such a site, yet it's not there,

All in all. I prefer FA. I'm on here daily anyway.
commishes just.. doesn't seem trustworthy. I mean, I used it before, as I said, and payment is not through them, but the lack of even basic features, the fact that they didn't react in any way to the bug report and so on just doesn't fill me with confidence.
It would've been a nice idea if whoever made it actually put some thought into it

EDIT: obviously, this is all from the customers perspective, and I never cared about adobtables, be it there or on FA

I second Leogarg.
I've bought through it a couple of times, but only cause the artists linked. I definitely don't enjoy browsing the site, but maybe just because I'm so used to FA and being able to sift through an artist's gallery to get a better feel for their quality.

Checked it, not touching it even with a ten feet pole and disposable cards. I am a bit more security aware than your average literate 'net user, and yhis place just screams "get pwned!".

Never heard of it.
