17-year-old Chicago rapper Chief Keef recently went on a twitter rant after Instagram removed his nasty X-rated photo of him having sex with a female.
"F-ck instagram dey took my s**t again #300," he tweeted after learning the sex act image had been removed.

"Stick My Fingas In Her Butt While I'm Gettin Brain Yea Ima Nasty B**ch Wat Chief Sosa #300," the Chicago native continued to rant.

"I like a b**ch with some lips like a deathtrap #300." "I'm wat u call a male version of a #SLUT!"

And under federal law (18 U.S.C. 2256), child pornography is defined as visual depiction, including any photograph, film, video, picture, or computer or computer-generated image or picture, whether made or produced by electronic, mechanical, or other means, of sexually explicit conduct, where the production of the visual depiction involves the use of a minor engaging in sexually explicit conduct; or the visual depiction is a digital image, computer image, or computer-generated image that is, or is indistinguishable from, that of a minor engaging in sexually explicit conduct; or the visual depiction has been created, adapted, or modified to appear that an identifiable minor is engaging in sexually explicit conduct.

And since the Feds are already investigating his actions, Chief might be in a lot of trouble for the X-rated pic.
