The first thing you will notice with some not all is they have the following characteristics with their profile.

1. The don't complete their profile(on occasion you may run across one that is filled out) still be mindful, if it doesn't feel right it probably isn't.
2. They post only one photo (really take a moment and look at the photo, then ask yourself does this look genuine. If it doesn't move on) follow your gut you won't go wrong.*Sincere men who are what I consider genuine post photos that show they have other interest, self-interest, and pic that look REAL and not off the internet. Always check what they post for pictures.
3. If they message you, they first try to peak your interest. Then they want to connect with you "outside" of this venue. They will even give you their phone number and email, kik or some other account so they can get your undivided attention. This is there goal...to capture your attention!
4.Let them know you don't chat outside of this venue. (They will work diligently and persistently to keep your attention and pressure you to leave this site. DO NOT DO IT. If they continue to contact you and harass you then you need to report them and block them.

Finally, Most importantly, if you follow your first mind (thought) you normally don't go wrong. If something feels off, then it probably is. Be safe, always remember to protect yourself first...and never, ever, give out your personal info to someone you don't trust or is/feels questionable.

Hope this helps!
