Millions of slightly unsavvy social media users now have regrets over revealing too much information over the internet, research has revealed.

A study into the online behaviour of 2000 over 18s found one third wish they had kept certain photographs or profile information to themselves.

Many of the 'over sharers' have been left red-faced after posting drunken photographs, posing in very little clothing and using inappropriate language - probably because half admit they aren’t exactly sure who many of their followers are.

In fact, the same amount said there are people following them online that they don't actually want to share their information with.

A surprising one in ten have even been pulled up by the boss after publicly moaning about work, and surprisingly, over one in 20 were told by a potential employer that they missed out on a job because they weren't impressed with photos they had seen online.

"There is a massive trend for people posting their whereabouts and achievements on a daily basis," a spokesperson for White Hat Media said.

"Research shows that the average person dips in and out of social media several times a day, sharing a wealth of information in the process.

"And it can be hard to remember what followers you have, and who you might be comfortable sharing intimate details with."

Other mishaps suffered by silly social-medians because of posting too much information include being caught having an affair, getting rumbled for pulling a 'sickie' and divulging dates of holidays.

In fact, six percent have been dumped because of something said or done online, five percent were caught two-timing someone and seven percent have had a all-too-public argument with their other half.

When it comes to content of slightly more regular posts, 'over sharers' admit they often share their proudest moments, how they are feeling and what they did at work, as well as where they are going, illnesses, thoughts on local news, news about friends and family and what they've bought that day.

Boasts about the children's achievements, gossiping about celebrities and what has upset them are also shared on an all-too-regular basis.

One fifth of people admit they give away too much online, with 53 percent admitting they wouldn't confide in many of their online friends if they saw them face-to-face.

A massive one in three said they would be embarrassed to learn certain friends or family had seen their photos or posts, while three in ten admitted looking back at their post and status updates and cringing.

But despite sharing a wealth of information online, only 44 percent are confident that the details they are posting are safe and secure, while 37 percent admit they are not online security savvy at all.

More than half of those polled think they should probably be more careful when it comes to sharing information online.
