This is not the first time some member is doing ban evasion and he does not get banned by moderators.
I remember few years ago I posted clear proof and connection between accounts (address and social media), that guy created many accounts but most of them never got banned.
As for IP bans, they are far from perfect, because I heard many examples of people who tried to register in forum for the first time and they received evil fee message.

Yeah sure, I think you deserve a medal for your ''contribution'', and you write forum posts like a real cave man.
