like some bro said, a lot of people get "tagged" on F***Book and don't even know it.
trust me, the corporate drones who run FB do not give a flying fuck about anyone's privacy. try to delete yr profile (NOT "deactivate"--FB's kind suggestion of how to get off their site which does NOTHING). even if u complete a successful delete-procedure, log on during 14 working days, even by accident, and yr active again. to get an idea of how intent FB is intent on keeping u, check their cease-and-desist letter on this site:
http://suicidemachine.org/
look for: "Please read the C&D letter from Facebook here!!!"
as they're going to IPO, of course they won't let you off.
as for your PRIVACY rights--people have been stalked, abused, robbed, even murdered from info gleaned from FB or partially from FB. FB's liability? you read their complete SLA when u signed up, right? the thing where you just clicked "Agree" without reading it? no one reads those.
it isn't enough to be careful as OTHERS can tag u on FB, even if yr acct isn't compromised. if someone gets access to yr acct, and has fotos of u, just think for a second about how all those "friends" u have wd react to the fotos? yr family? yr SO?
ya know, i might be paranoid. u might be posting all yr Wanchai pix and be juuuuuuust fine. but once those pix are on the Net, they can go anywhere.
last i checked, 2/3rds of HK employers checked job-applicants' FB accts (92% of HK is on FB). if this thing had existed when i was a teenager, i wd NEVER have gotten a job. but pix of u and WGs, partying or whatever, posted by u or someone else...imagine yr mom or SO having a close look. comfortable with that?
seriously, think about it. Our Hobby and social media do not mix. if someone decides they don't like u anymore and they want to make yr life difficult, if they've got yr profile and a bunch of pix...just THINK ABOUT IT.
call me paranoid: i'd rather be paranoid than busted.
