Here's another take on things. If u've met someone on a dating website, and u are dating each other and are in the early stages of dating...DELETE UR PROFILE!!! no need to hide it. This is a free website and u can create another one again and just as easily!
Sorry, it's not the cut and dry.
My profile does a lot more than just hangs here trolling for women. I have friends list, I'm on mailing list for POF events. I have frineds on here that let me know about parties.
I've done the "delete when met someone". Three months later, back on here again starting from scratch.
I connected with someone that I had made a favorite a year ago.
There is no way I'd tell anyone to delete their profile in early stages.
When I'm with someone, I hide my profile, and state not interested. And when I get women writing me, I tell them I'm not looking. I don't need a watchdog to tell me to do the right thing.
