Currently, Instagram appears to be flooded with images of various fruits, pointing to a site that advertises a "miracle fruit diet". The spam attack links to a fake BBC page, typically via a bit.ly link. The "BBC" page features an article touting the power of the advertised diet scheme.

It appears that compromissed Instagram accounts are the source of the spam. The accounts were compromissed using phishing e-mails as some reports indicate. In addition to posting the images, the users profile URL is also changed to the spam website.
