This is purely subjective, but to me I'm guessing it depends on what they advertise as?
I actually have a review from a week or so ago I need to write which potentially crosses the line (and may if I see her again before posting). Advertises as massage on VS, nothing ticked to imply more than a probable happy ending, but the happy ending was done orally and afterwards she said full service would have happened as well if I hadn't already popped.
I'm still leaning towards posting in in massages when the time comes, mainly because (I think) those reviews are only visible by signed in members, so less is given away about the otherwise genuine massage parlours who do a bit extra rather than those who blatantly advertise it.
