Yes, if it's too good to be true, don't bother, and specially in BP.
Lots of girls "borrow" pics 'cause they are not attractive enough or want to avoid to be discovered by family/friends, but also because they have bad reviews or are just scammers.

Although some good ladies (TER reviewed) post on BP from time to time. Use the search keyword "review*" or "TER" and you can get the TER IDs from those who have reviews, and then make a decision. I once met a BP girl, but has good reviews and also she had a professional website and TER reviews, that was a exception to my rule...

I'd say you can get high quality escorts in Boston starting at 300/hr, but with some exceptions in the 250 (RSG and some Indies). Less than that, I'd say it's very rare and not worth the risk
