I know the blatent ones like asking me for money really quick. I have some iron rules about what I will do and won't do. So if they are scammers I guess they don't want to get to know me here for a bit before going off site.
I also will throw someone for a loop in Voice chat by asking them to turn on their webcam. That usually will spook the fakes in a hurry.. They are gone in a blink of an eye. I had one guy when I asked that a couple of months ago end the conversation and block me. I kind of figured he wasn't who he said he was...
