Just noticed a change but not sure when this took place - a pity because it was quite useful.
It relates to "Verifiation Picture".
You used to be able to check a couple of boxes on the main Profile tab, which were (something like)
- Has Verification Picture
- That you can view
Seems to have been replaced with just "Fully Verified members only" - maybe that was there before, I don't remember.
Girls could always submit a verification picture but block you viewing it, but a small number never did, or didn't realise that they could.
