Errrr hell no ... take from my comment what you may one can only speak of personal experiences and in the "mature aunty" type punts which I dabble in say once or twice a year and then depends on the mood was a great fuck and even better BJ with cim. Have not reviewed her since I saw her long before I joined UKP
I take from your comment that 3-4 attempts is super flaky,
I also take it that lots of girls have 'regulars' but it's really bad form to completely blank a confirmed punt on account of a 'regular'
you're in no position to make that assertion on her behalf as you really don't know
there's nothing against reviewing a punt that happened before you joined UKP, there may be interest regardless, what does she look like, how discreet was her location, attitude, hygiene and all that, go for it
