If an escort is reviewed as having a 7 overall rating, what does this usually imply? Does this imply that she doesn't offer FS? Massage only or HJ or BJ only?

If you look at the review posting guidelines, you will see that an escort can get OVER 7 only if she does either BBBJ, DFK, greek, is bi or can go with 2 guys at the same time. Which means that an escort that gets 7 does everything (FS included) EXCEPT what is stated above.
