Nothing is private, as long as it is on the Internet. Be careful of who you may offend, as your reputation, career and even family can be ruined on Facebook.

In a report in The New Paper today (Mar 4), a Singaporean businessman's reputation took a turn for the worse when his jilted Hong Kong lover went on an online 'kiss and tell' rampage on Facebook.

The man, a 42-year-old general manager, is married with a son, but started seeing the woman after meeting her at a bar on one of his frequent Hong Kong business trips.

When things turned sour, the 28-year-old woman uploaded pictures of them together, including those of them in bed. These were uploaded on her Facebook page in a bid to shame her ex-lover.

STOMPer Face-Booked shares his views:

"We all have Facebook, and the 'danger' of being involved in a public online campaign by your Facebook friend looms...especially if you have possibly offended someone.

"So be careful of the things you share online, and allow people to post of you -- remember, nothing is private as long as it is found online.

"I read about this man whose reputation was shattered to smithereens by his jilted HK lover, and one of the means she used was Facebook, and even emails to his workplace.

"He is married with a son, and by now, his friends, colleagues and family knows about it -- what a way to ruin a career, a life, and a family.

STOMPer NoFace also shares some tips on how to limit 'smearing':

"Actually, after coming across this article today, I was not surprised. It's pretty common for people to embark on such 'smear campaigns'.

"It's pretty common to have unwanted pictures of yourself posted on social networking sites, especially Facebook.

"Some of these photos are also 'damaging to our reputation', if you are sensitive to seeing 'unglam' pictures of yourself online.

"You can pretend you don't have a Facebook account, or label all your information as private, but you cannot escape having 'smear campaigns' in your name especially if you have offended someone.

"It's not limited to Facebook, there are other avenues people can do it, be it online on other sites, or through offline means.

"But of course, on Facebook it's public, linked to your friends, family and even colleagues -- and sometimes the circulated info can go viral.

"I'm sure you wouldn't want to be the main star of a viral video, would you? I sure wouldn't.

"So guys, keep your hands and legs to yourself and be careful not to step on any toes."
