I wouldn't put up a red flag on this one, but definitely a yellow.

1) Partly understandable, but also could be a setup.

2) Means nothing these days. The comic strip XKCD once posted "anatomy of a cell phone number:" the first three digits represent where you lived in 2005, then seven random numbers.  

3) Several CL listings a day is, to me, a sign of desperation. That is NOT consistent with "need a little extra money every now and then." Especially if she doesn't list her restricted hours because of the day job.

4) This is as close to a red flag as I can see. If she is so careless about keeping her private and professional life separate that you know her name, marital and parental status, and know her husband's name and demeanor, she's over-sharing. And that really can't have many good explanations.  

In your shoes, I'd be tempted to come up with some kind of excuse for breaking things off that would encourage her to leave you alone, too. Maybe something along the lines of a friend or relative who's a cop has discreetly informed you that you're being eyed as a hobbyist, and you might be being watched. Or a medical condition has developed, like a back injury or something. Or you've been subpoenaed as a potential witness in some legal case, and you gotta keep your nose clean. Or you've applied for a government job, and there could be a background check. Or your new boss is a religious fanatic who's already making life hell for some employees who are "sinners." Just something that makes it seem like it isn't your idea, but unfortunate circumstances. And makes her want to respect it and keep her distance, too.

Just keep it simple, avoid details, and sound regretful, but not too elaborate. No cancer, no hepatitis, no STDs, no arrests, no job as a cop, no religious conversion, just basic.

Hell, we have some wonderful resources here. Why not ask some of the ladies if they agree with your concerns, and if so, how would they recommend proceeding? Hell, ladies, if you like my suggestion, perhaps you could offer some particular scenarios that you'd find persuasive?

Go with that gut feeling you're having and remember  if it waddles like a duck and quacks like a  fuckin  A it's a duck 💋

None of this adds up to anything good or positive in anyway for anyone. Use some self control and step away from this mess before you end up in a heap of "oh shit".

No reviews, and pimp lurking nearby? Sounds like he plans to rip you off, but feels a little guilty so she's trying to warn you.

I would Bail out on this one! There are so many women out there, be patient, do your homework, research everything then act. Use your head not the little one either! Good Luck.
