@Sunshine20,
Some of those profiles are fillers and are old.
Some might be images from another website or location as well.
Some dating sites are really recruiter sites that analyzes people, looking for specific minded folks.
You need to talk with the person and or meet up in a public location at least.
Like a viable location that is populated most of the time, then have a real conversation.
Honest to gosh my brother does this dating app bs, and get bs based off his likes. He just went with the first girl he could found just to get his head wet.
I do not like those apps at all. My advice you want to look for somebody,
then go to a tourist location or some place where people walk around, like
the beach or park, or city-hall. Maybe somebody would or could talk with you. Some parties like art esque might have some interesting people, or even free live public events. In my area they have one meant for all kinds of age groups ( literally round the clock ), so you will not have to worry about spending money.
