What's being done to thwart profile miners and scammers? The expectation is we chat with the real person. Not advocating ID verification, but if you pay real money then a billing address provides sufficient info, and if you don't have $300 for years of memories then please go away.

Good point. So far I only have email verification. There is no billing yet, everything is free currently. On long term I plan to offer convenience features and for example to possibility to create custom question sets. Those gonna be premium features and I will offer that way cheaper than the competitors. It's a good idea that this could also be the verification level and maybe I could add a matching criteria that only verified premium users match with each other.
