I think the "not [as] advertised" covers a lot of ground and that was what I was really questioning.
I'm certainly all for telling others about the good experiences that you think they will also greatly enjoy. In the end, that is what everyone if looking for in my view. No one is here not to spend their money, they just want to spend it well.
So how wide is your not as advertised band between okay time, not a waste of money but nothing to "write home about" and so far from reality that very few will like it? I get that writing a review that basically says, your getting pretty much what you expected if you were TOFTT might be more trouble than its worth. But I think depending on where in the spectrum between an average/okay experience to a waste of my money experience not writing the review will have implications for both side.
So I was curious about where you might be drawing the line with regards to writing a review when it's not going to be a strong recommendation to see the provider.
When I was reviewing I was a bit like you describe but I would (though only needed to do so once) write reviews if I thought others would find they were not getting what they should be expecting from the provider -- the degree of "not as advertised" was too far from what someone should expect in advertising. But if all I was going to do is write "just like any other K-girl you might see at this agency" (which would be 7/7 for me) I might not write that review and certainly not write if if there were already 5 or so reviews published. But if there were no reviews I was more likely to write one for two reasons.
"just like any other k-girl" is a very YEMV situation and while I thought it was okay but not a memorable session some others will likely have a better experience than me. But no reviews and TOFTT cases are considered high risk by most so mongers often avoid those situations. And, no reviews when the girls been around for a little while are generally pretty bad warning flags (or used to be). So not posting a review in such cases seems to be unhelpful to both sides here. I say that as an observation of outcome, not as some judgement that you are doing harm or something like that. I stopped writing reviews so making that type of charge would be absurd for me to do.
So to recap as the long-winded comment might not be well written. I was not too different than you I think in terms of my approach to review writing. But the decision not to write a first review, under the conditions you describe, seems ambiguous to me. Why the reluctance, if that is the right description, in writing a first review if you cannot write a very positive review? Seems like you're saying it's not due to some fear of being BLed by the agency/booker/k-girl but something else. Also, does that hold if you think "not as advertised" was in the area of "completely misleading and no one will think that ad was even remotely representative" of who you will be meeting?
