The owners of meme-sharing app and site iFunny are making its volunteer moderators sign nondisclosure agreements after the arrests this month of two of its users for allegedly threatening mass violence on the platform.

According to a copy of the NDA that BuzzFeed News received — which iFunny’s owners are calling a “Volunteer Confidentiality Agreement” — moderators would no longer be allowed to discuss the inner workings of the app. “Volunteer agrees not to use Confidential Information and/or Proprietary Data for the benefit of any other person, corporation or entity, other than the Principal, during the term of Volunteer’s work with Principal, or any time thereafter,” the agreement reads.
