Kim Kardashian is unimpressed with Instagram's new rules.

The reality star has threatened to quit the photo sharing site if the company doesn't revise their new terms of service policy, which initially stated it would allow them to sell users' images to outside companies without financial compensation.

She told TMZ: ''I just don't think they should have the right to sell [our photos] to advertising companies on our behalf. What if we don't want to advertise what they want? I just hope they revise it.''

Instagram have since apologised for their ''confusing'' TOS policy and are currently revising the wording, but Kim is unconvinced and is furious her favourite social networking site could be set to invade her privacy.

The buxom brunette has allegedly been telling friends she has vowed to leave the site and take her hordes of followers along with her.

The glamorous 32-year-old socialite - who is dating rapper Kanye West - is by far the site's most popular user and has 5,726,343 followers who enjoy regular updates on her fashion and beauty choices.

Tailing behind Kim are Justin Bieber and President Barack Obama with 4,366,729 and 1,834,079 followers respectively.
