What is everyone's opinion of plenty of fish dating site?

I was recommended this site by ironically someone on Mylot, so I signed up, haven't had any responses at all, mind you my track record for dating site is appalling! So much so that I just gave up on them, they are not for me. I am not looking for a relationship anyhow, just friendship. I get the daily emails from them, but a few days I marked them as spam because I was bored with getting them no responses. I should delete my account.
