You cannot do it from the mobile site. You need to use your search, example safari and look up pof desktop version and go to the help in the top left. It will walk you thru it, if I remember correctly. Good luck
Complain about scams repetivly, they will erase your account, if they are not in a good day, just tell them when you report they are linked with scammers, these guys dont like to listen the truth
Yeah, you cant do it on your phone. You have to be on a laptop or pc to do so. Just go to "help" and there's faq's that say "delete or disable account" its fairly easy from there. I wish there was an option to click on when being asked "why are you leaving?" My answer: this site sucks. But alas, not available.
