That is racist .Romania has notoriously bad reputation in internet business so it's no wonder that everyone is blocking them. Even in Setti's list 90% of fake servers are hosted by Romanians. Poland and Romania should be restricted to their private network without access to outside world
Regarding fake servers, from my point of view, you can ban any ip with more that 3 - 4 active servers. (tough, in some cases, there are more servers on the same ip, it's very rare).
