Use your common sense when going for totally free dating!
Otherwise, stick with more reputable sites like (more casual) or e Harmony (more serious).
To make a dating site work, the site must first have viable options for people to date.
I've clicked on two profiles that contained no info at all.
(haven't even seen a button for messages), was I too greedy looking at two profiles within 10 minutes?
Plenty Of Fish is one for the list of memberships in my opinion, works well in Stockport. There's a list of rules, and when people report you for breaking them, or when the system thinks you might be breaking them.. It seems to be doing a good job at it blocking most of the bad behaviour, but it's also deleting people with good intentions.
I also really like wejustfit.com, in case youre interested in other trust worthy options to add to your own list! I was in the middle of filling out the questions, but had to go to work. My actual review stops here, since there is nothing more i can review.
