Tried this site and found that it can be extremely expensive. It costs 10 credits to send and read messages. You will have a lot of people messaging you with their hi's which cost credit. I didn't even get to the stage of uploading a profile and there were so many people who wrote to me. Conversations with the people on it seemed unnatural and I came to the conclusion they were either bots, or paid guys working to give replies.
Pros
good for killing time.
Cons
Probably bots/ fake profiles.
Sneaky billing in terms and conditions (fall below a certain credit will be charged for 1000 credits)
expensive
Must call a number to cancel, and they try to convince you to stay.
This is a Con website.
