Our server we run has certain plugins for admin use only but we received a file called community_server_readme.txt in our plugins folder basically saying some of our plugins don't meet the "Unofficial Community Suggested Guidelines" but the plugins we have are for Admins to use, we have ==PlayerAdministration, Entity Owner, No Give Notice, Auto Broadcast, Master Key, Save Announcer and Night Vision==. These plugins are only accesible by our staff and not the players I can understand maybe ==Night Vision, Save Announcer and possibly Auto Broadcast== but the rest I am not sure why it says they're not apart of the guidelines they're strictly for administration purposes. We would like to put our server back to community but we just wanna make sure it's alright to keep these plugins first before we do.

Facepunch allows admin tools, which most of those would be seen as not as far as I know. Anything user-facing that changes the look or feel of the game would not be allowed. The message you saw is from your host though, so it is up to them and their discression.

Save Announcer and Auto Broadcast is probabaly what got you removed from community

Maybe NoGiveNotices too to prevent abuse
