It was two days before Christmas mate, I was too busy to write one. Is there not something to the [unwritten] rules where there's a time limit to post one, or can I do it retroactively?
You absolutely can post "retroactively" (all posts are that anyway). No one expects you to always do a review within a few days or even weeks of the punt (and there's sometimes good reasons not to post sooner too). A review from only 2 months ago is definitely recent in pretty much everyone's eyes, as such a review would definitely still be helpful (e.g. I presume you still read reviews that are over a couple of months old).
The site rules state that you can opost a positive review as long as it's within 12 months of the punt (it's a very new rule too). There's no time limit on negatives or neutrals.
Not having a go at you, but punters in general overestimate the money the girls make, there are just way more girls willing to sell sex than men wishing to buy,
Rubbish - there's far more demand than there is supply. There are plenty of ugly women and dodgy Roms etc out there who seem to be busy/have plenty of feedback on AW (which will just be the tip of the iceberg). There are other sources like Vivastreet but they wouldn't be in business if there wasn't plenty of demand out there.
The continued existence/success of Roma and many other WGs who have lots of negative reviews on here (and even feedback on AW) is just part of the proof.
If what you claim is true then most WGs would be even easier to book (especially at "peak" times), many of them would have better comms, being stood up would be much rarer, prices would be lower, being rushed or double booked would be rarer and typical/average service standards would be higher (necessary in order to retain clients to make decent money).
You can just ask WGs yourself for proof. While most will dispute the somewhat common (and mostly false) perception of them being anywhere near very busy (except the few that are of course), most will still say they see a good/healthy number of clients. If you want to "see" the demand for yourself just ask a "typical" WG (one who doesn't look/sound amazing or have lots of reviews or feedback) and ask them to briefly show you an overview of their texts, call logs and AW inbox. As they'll tell you, a lot/most of it is from idiots and time wasters but there's still quite a lot of genuine punters.
Only being a "sugar baby" (on sites like SA) does supply exceed demand (for obvious reasons).
Nonethless, I agree that many punters overestimate how much WGs make and I agree with the rest of your post.
