7Cups does have a rating per listener, but they have some serious issues on that site as well.   Firstly they have a built-in censorship mechanism that scans every word entered and if it detects something, it blocks that chat message and gives a warning.   My problem with this is it invalidates confidentiality.   Every listener and venter in 7cups and Blah have the power to disconnect if they feel threatened or uncomfortable.   Secondly, it would be easy to circumvent the censors in 7cups by inserting numbers for letters, or omitting letters.    I do believe in my experience that you will get better results at 7Cups, but as always, if someone has a serious mental health related problem, they should seek out licensed professionals in person.
