In my opinion experienced users should lead by example and to show a willingness to compromise.
Who exactly are the experienced users that should lead by example in the Russian section? [...]
Reputable forum members were meant, which have years of experience on the forum, not only in Russian locale.
They could remind other users that is need to make trust lists with responsibility.
Being useful is not the same as being trustworthy.
I think this warning might be added on the
Trust settings page.
