Warthunder custom server bugs and DDOS problems

Gaijin PLEASE fix ur game. If any if you play custom chill servers u might know what im talking about. Ever since the latest major update, there has been a major name bug. Where if someone leaves the custom, it will swap their name with someone elses. So randomly youll have a different name and its annoying. 2nd of all…the DDOS problems. There have been multiple players coming into multiple customs to DDOS it. I thought gaijin would have had software to get rid of these goofs?
