Yep. I mean you can set things like location preference, age preference, type of relationship you're interested in, and so forth to filter people out...and it's supposed to help filter those people from you too but people can still search for your particular demographic anyways. So, even if I set certain things to deter people, I got a lot of messages from people right off the bat that would be absolutely no go for me (no offense to them personally just sort of deal breaker things). So, I had messages from people daily that were in my set preferences but then I had people that were...
much much older people, people not even in the same country let alone state, people that were looking for a "third" in their relationships lol...Then for the people that actually were in my set "criteria" was sort of a 50/50 with being normal first messages or downright perverted first messages...
I also live in a pretty big city so I guess you can say there's a lot of people that were in my initial city alone and surrounding areas.
I really didn't stay on for long though. In total, I probably kept my profile active for two weeks. So, I could have just been having an influx from people seeing a new profile come up because I did see a lot of " hey youre new" messages. I really didn't have the time to even search for profiles on my own between going through the ones messaging me daily. However, even when I did look, most of the people through a quick search were people already messaging me. Most, not all, definitely do not put much into following people's restrictions or reading their profiles so, in a sense, you're right that a lot of people will take a stab or test to see if you'll still be interested.
