ComiXology has removed 56 titles from its iOS app this week -- they range from Angry Youth Comix to Sex to The Boys: Herogasm -- to adhere to Apple App Store policies. They're still available for purchase from comiXology.com.

"In order to comply with the Apple App Store guidelines regarding adult or inappropriate content, some new releases were rejected for our iOS app this week," a statement on the comiXology blog reads. "In addition, certain previously released titles that fall outside of these guidelines were also rejected and will be removed from sale."

The announcement comes a little more than a month after the digital-comics distribution platform rejected Saga #12 in an effort to adhere to Apple policies, an action originally attributed to the computer giant. In the aftermath, Image asked that Black Kiss II, XXXombies and Sex #1 be revisited, resulting in all three being approved for the comiXology and Image Comics iOS apps. Now, however,  all three have been removed.

The list of removed titles also includes Jess Fink's Chester 5000, Reed Waller and Kate Worley's classic Omaha the Cat Dancer, Johnny Ryan's Prison Pit and the gay-comics anthology No Straight Lines, which features the work of Alison Bechdel, Howard Cruse and Eric Shanower, among others.

Update (11:50 a.m.): ComiXology contacted ROBOT 6 to clarify that it was notified by Apple that those titles didn't meet the App Store content guidelines, and therefore were pulled from the iOS app.
