I am someone who is trying to advertise something on Reddit and I recently hired some people to use their 10+ year old 2k+ comment karma accounts to help me with this. (accounts were u/blinx0rz and u/AggressiveShirt4430). However after a week or so all their accounts were suspended for ban evasion by Reddit admins. I never knew ban evasion could be applied manually by admins. I always thought this was done programmatically.
