Regarding the nickname "Euk-geun"

As shown in the photos below, "Euk-geun" has frequently changed their nickname to hide their identity.
Even before the 2022 presidential election, this user was using a nickname to disparage Lee Jae-myung as "Lee Joe-myung" (a play on words implying he is a criminal).
I don't know whose alt account this is, but
looking at the stance of their posts, they are almost identical to yoda.
Criticizing Lee Jae-myung, let's go Cho Kuk Party!
