I was looking this site up after receiving an email from them saying I had joined their site, when I hadn't - first sign of scam, obviously. The next was that, the user name it had for me was essentially what I have on this site and most others - including Elance; however the email it was sent to is not affiliated with Elance (at least to my recollection, it isn't) and to top it off, the last bit the screen name, the numbers, were out of sequence; which I'm not sure what to make of, seeing as how, if the data had been ripped off from my Elance account, it would have been correct.
As luck should be, in this case at least, I have not been lucky enough to win any project bids and my activity on Elance is very low; so my information stored there isn't all that extensive, or else I'd be worried what information they might have gotten. Even then, I'll probably do a double check of that account to see what's all there and if there is anything of importance that I've forgotten was attached to that site.
