I usually prefer not to give too much personal information at the internet and not posting too many photos.
The internet is the wild wild west folks. anything's possible to find out about anyone, with enough doggedness. Your electronic footprint is a fact of life now. I pretty much don't really give a damn who knows who I am, or where I am. But.. I don't leave banking things in the computer, I change passwords regularly, and I run an IP logger in my computers to log which IPs connect to it. Basic good sense and care , plus learning a few advanced computer security softwares is advisable. Your cellphone is a leak. Do you know that 99% of all cellphones has built in GPS? Don't just scream and yank hair believing that computers are the only thing that youi need to be worried about
