I think that is the basis (true or not) of why so many dating websites have strict security warnings to their end users. I have met a few people who fibbed about certain things, but only one that was a stalker type (and he quickly went away after a restraining order was placed).
I heard the one about the guy finding out his mother was the person he had been talking to on a dating website. Imagine all the naughty(words not pictures) emails that were exchanged. I would be beyond horrified! I would also need some major counciling after that ordeal!
I agree, I would be terrified if that was me. Imagine if picture were involved as well. I would never use the internet again! Fortunately my parents aren't on the internet enough for me to have to ever worry about such a thing.
