The sad reality is that the majority of all metin2 private servers of any kind whether it be oldschool, speed etc...are data farms and they don't even last long. 

Gameforge should create metin2 classic era servers with max. lv 99, the way it was in the late 2000s, this would automatically attract old players as well as new ones because no new player is interested in the current version of metin2. Streamers who played the original metin2 back in the day would start streaming these classic servers and give it notoriety which would be beneficial to both Gameforge as well as the servers.
