Stop Scammers

I've noticed that scammers are active on the Internet, e.g. Facebook and here.

This man here posted a photo of an American officer Ivan Lopez who shot himself last year.
He writes to women that he is an American general and that he is divorced and wants to marry.
After promising to marry such people he invents some reason to ask women for money. This is a well-known scheme. Such people can be easily exposed. Just google their photos and you'll see where it was taken from. Beware of them.
How many of them are around?

You are right I think there are many of them,and we should be careful when connecting to people via the internet to check that they are really who they claim.
