How much this affect the legality of hosting a game server? Even a vanilla server , without any databases to co-operate can store IP address data of all connected clients to a .log file, if you enable the logging via "log on" command in server.cfg. Are we obliged to introduce a MOTD or plugin that is exactly like all these "we have updated our privacy policy" and "we don't store your data like IP address for more than a week" and having players to accept it in order to keep playing on the server, otherwise disconnect?
