kik public groups

How in the heck do these things work? I was able to find the hookup groups easily enough by searching on my city, but as soon as I enter, I immediately get hit up by ladies that seem very scammy and want electronic transfers up front (hell no).
I usually will look at the profile pictures. If the room is full of modelesque professional photos, it's full of spam girls. If they look pretty average to hot and look like selfies, you're in the right group. Kik is hit or miss
