Messages from the pilot of missing Malaysia Airlines flight MH370 have revealed a creepy man who obsessed over twin sister models' social media profiles.

Captain Zaharie Ahmad Shah was the pilot-in-command when the plane carrying 238 other passengers and crew vanished in March 2014.

But his social media activities have been revealed on Sunday, giving an insight into the mental status of a man psychologists say was "self-destructive", the Daily Mail reports.

In the 12 months before the Boeing 777 went missing, Zaharie stalked the Facebook pages of Malaysian twin sister models, leaving sexually suggestive comments.

Throughout 2013, the 53-year-old made 97 separate Facebook comments directed at Qi Min Lan.

A vast majority of his messages were ignored.

Zaharie implored the twins to come to Kuala Lumpur, where he lived with his wife.

'When in KL," he wrote in another.

"How about KL?' he persisted, but got no reply.

In another, where Qi Min Lan posted a photo of herself in a bathrobe, he wrote: "Just shower?"

In one of nearly 100 posts, he asked Qi Min Lan if she had just come out of the shower. Photo /Facebook

Zaharie was described as 'kind' and 'easy going' by his friends, but his social media reveals a reckless side of the pilot, the Daily Telegraph reports.

On top of his obsessive messages to the girls, Zaharie frequently criticised the Malaysian government, which happens to own the airline he worked for.

On his own public Facebook page, Zaharie labelling then prime minister Najib Razak a 'moron'.

In April 2013, leading up to the Malaysian elections, Zaharie posted 119 times, all in reflection of his disgust with the Naijb government.

The following month, after the Najib party secured another five-year term, Zaharie wrote: 'There is a rebel in each and every one of us. Let it out!'
