Why don't you check some of these reviewers to see if they had written other reviews?  If any of the reviews jump out at you, PM the reviewer and ask questions.

Post a link to the review so we can take a look.

I found my answer a few pages back. Thanks!

I should have done some more searching. Thanks for the help though.

I would look at the reviewers.  If each of the three reviewers have multiple reviews to their credit, then you are safe.  If each reviewer only has one review, I'd be suspicious.

Also, if the reviews were all done recently, that might (or might not) be a warning sign.  OTOH, it could just mean that she's new.

right now the Chicago area is rife with busts, but Boston is not so bad. (Watch our for New Hampshire however.)

Multiple reviews (usually 5 or 6) by reviewers with a history of reviews (again, 5 or 6) over a period of time (at least 6 weeks) and you should be safe.  The only variable above that I would consider lowering the number is the time span over which the reviews have been written.  There could be a review at the beginning, middle, and end of a month.  You can always PM the reviewers to get a better understanding about the lady.

But anything over 850 would lead me to question their virtue.
