When you make advertisements for your app that probably indicates that
nobody cares if you got moderator
And don't you always start drama on the forums and even have been banned for it?
Sorry, but
"Lenny Boy and his gang DONT Post here!"
From my understanding you can't stop people from commenting on a staff app, on top of that you only named a single person being lenny, saying "his gang" isn't naming names. If you were able to stop people replying to an app you could easily block off anyone who may have the ability to raise issue with you getting staff which would be incredibly dangerous for a community.
As I stated before blocking people from giving criticism on your actions is incredibly immature and shows insecurity in your actions.
