Ok ok, that's a little bit clear for me, but this french server said for example ; "If we don't have enough donation before this night, the server will be close". And they said that again an again during all the evening with a link to the forum where you can donate.
I understand donation is very important for server to "survive" but this french server forces players to donate to play the next month. Futhermore i heard this server did this 3/4 months ago and they received a warning from Bohemia to stop admin send message like this.
This server is like a "Pay to win" or "Pay to 'play' " !
