Actually I may be wrong looking at past events.

Looking back actually it seems yes they should be kept private.

Many advocated red trust was given to bill gator for publishing LFC bitcoin admission that lauda bullies him to exclude bill gator from default trust.

I think many including lauda said this publishing of PM is a red tag offence.

Many members say this is a red tag offence. So unless it is to prove someone scammed it is not allowed.


Saltyspittoon admin for 6 years say it is not allowed
