Three years ago I was on this site on a free account. Was matched (mutually liked) my a fairly attractive 45-year old woman from my area. Sent a couple of messages to her, never received a reply...
I reopened my account the other day. Guess what, same woman, same picture, same age, mutual like...
I am thinking this is too much of a coincidence.
Other than that, the user base of real members in my area (Belgium) is extremely limited, and the site is quite badly designed from the UX point of view. If you are in an area with a reasonable critical mass of existing users, and if you can tolerate the weird UI, then by all means make your free account...
