I just looked at Lemmygrad.ml. The rules on that site say "be respectful".
Your attached picture shows you are not respectful at all. You are supporting Putin, a dictator, who rigs elections, and who orders assassinations of political opponents (Navalny) and former Russian intelligence agents (Skripal, Litvinenko).
And of course Putin has in no way been respectful towards Ukraine. Invading Crimea in 2014, and the larger invasion in 2022.
So, you are being disrespectful towards Ukraine, and therefore you're not embodying the stated rules and values of your Lemmygrad server.
