IDK, it just seems to me that almost everyone who simply says "HI", or gives no details usually end up asking for something...

I Mean Please,
#1) If you don't have a back story, along with other information, like the questions answered on your bio, that's my 1st warning of a possible scam.

#2) Are you a begger? If not, why are you asking me for anything, especially b4 we meet.

#3) Why do you want to leave this safe haven and go elsewhere b4 we've chatted a couple times?

That alone is a dead giveaway that you're hunting for some poor fool to take advantage of...

#4) Sending provocative pics, when I haven't asked for any.

#5) saying that you're looking for a long term relationship, or something serious - then following them to a different site so they can send nudes & highly provocative pics.
lol, I wonder how many hundreds or thousands of people have seen my "wife to be" in the nude? And they think they're marriage material.!? HUH?

I'm trying to be careful, so I don't break the rules...
Yet, in my experience, these are good indicators of people who have an interest moreso in what they can scam from you, and not you - yourself...
