From what I've heard a lot of the girl profiles on the site are fake, and bots running those accounts will send you messages saying that their "interested" in you, but of course to actually reply to them you have to get a paid subscription- total scam, the site owners are just trying to get your money by having those bots send you messages to try and trick you, just really scummy stuff all around.
In general it's just better to meet people at places like conventions or group meet ups or other stuff like that, many relationships that start on online dating sites don't usually end up lasting too long
