My blacklist is longer that my hotlist
Do you find it works for you?
These things will vary depending on area. But my general advice if your AW searching isn't giving you results you want would be to consider multiple hotlists and
multiple saved searches. Multiple saved searches allow you to skim very quickly through prossies using highest then descending criteria. My highest is 18-21, max 90 for 30 minutes, max distance 1 mile, no Romanians.You could refine it with various deal-breakers like OWO, CIM, but the profile declarations on these have poor accuracy. Using saved searches and a separate window with UKP, I can flick through probables by checking UKP ratings, either adding to a new hotlist I call "now" and relegating others to a "no way" (my 'blacklist' hotlist for undesirables).
If I don't get what I want I click on my next, slightly broader hotlist, similar, but 5-mile radius, 18-28 but arranged by age.
Having a "no way" hotlist instead of a blacklist also saves me time as things like 'bareback', 'known scammer', 'timewaster' can be added in the notes so I know why the tasty-looking profile is really to be avoided, and without searching through reviews again.
I discarded AW blacklist facility long ago, but if it works for you, good for you.
