@lukmarcus - I have posted in the Polish section without using Polish language before and got a warning. I think this would be the best thing to do in future, rather than react with instant flag. For repeat offenders, no problem - flag away!
I appreciate your point about wanting a place for exclusively Polish language, and even though Polish is not my native tongue (and a bloody difficult language!), when I post about Poland using Polish tag, I make an effort to translate my words.
A (pedantic) suggestion to avoid this in the future: you could always transition the tag to Polski, as foreigners are unlikely to use this, and it would avoid any ambiguity as it is in factreal Polish ;P I know this is what happened with the tag Deutsch - any non-German language posts are politely requested to use the tag Germany instead.
Pozdrawiam!
But I always take the flag off when user remove #polish tag! That's the only way people would listen. And as I said in another comment:
What tag should be used by Russian, Korean or Chinese?
We seem to be talking across two reply threads, which is a bit confusing, but I like chaos, so im gonna run with it!
When I made the mistake of tagging Polish and not writing in Polish, you just gave a warning with explanation of the policy, and that was fine. I think flagging for the first offence is an over-reaction and a bit unwelcoming & unnecessary, especially as most users on here are keen not to upset and people and will play by the rules.
