Facebook disabled two admin accounts of the «Info Portal» without any reason

Today Facebook disabled two admin accounts of the «Info Portal» page without explanations of any reason.

Facebook administration sent the following message: «We have determined that you are ineligible to use Facebook. Unfortunately, for safety and security reasons, we cannot provide additional information as to why your account was disabled. This decision is final».

It is very strange decision because both admins had real accounts on Facebook for a long time – 8 and 2 years and had never been banned for violation of norms of Facebook community.
