I'm starting to wonder - I've just seen the second response from a new user within 24 hours claiming the employer in https://sqa.stackexchange.com/questions/5867/applied-and-got-interview-within-hours-im-wondering-if-this-sqa-company-is-a-s is a good company and not at all a scam. Neither new user has added more than the bare minimum needed to create a profile.
Is it suspicious? Yes. But there doesn't appear to be anything against our policy. All the information available indicates they're as distinct as two accounts might be expected to be. They all appear to be from Southern California, which makes sense as the company in question publicly states on their website that they are as well.
So it is possible that someone at the company went "Hey, we got some people saying we're shady. Are a couple guys willing to go share their experience with us?" In fact, I'd say it's likely! But that begs the question of whether or not that's a bad thing. If they work there, I'd say they most certainly have the information the OP is looking for. If they're omitting or providing misleading or inaccurate information, it's difficult to tell, and impossible to prove.
