Okay, so with this ban, Serinus has effectively placed himself as an Admin of lemmy.world itself.He is stating positions for Lemmy.world itself, not just himself or his communities. Kaplan and other admins like @Ruud@lemmy.world are not stepping in and not criticising his behavior. With this behavior ongoing, it must be approved from the top level down or that the admins are totally out to lunch and not capable/willing of stepping in.
Moreover, a bot exists and has been talked about in the past. I was given access to it when I was on Lemmy.world. The bot was created by KingOfFlorda to allow for users like myself and Jordan to be able to deal with CSAM and other extremely bad actors when the admins were not available. There is no reason to believe that Serinus does not have access to the bot. The bot in question allows a non-admin user to apply an instance level ban to someone.
It was with this bot that you were banned from the instance.

You were not banned from an Admin account, you were banned from the bot account.
@MrKaplan@lemmy.world and @Ruud@lemmy.world have now, in effect, made @Serinus@lemmy.world an admin by allowing him to repeatedly post positions on behalf of Lemmy.world with stuff such as this:

In conclusion, Lemmy.world can now no longer be trusted for any admin decision. They are not being transparent with their decisions or even who their admins and those who have admin abilities are. They are willing to give total control of the website to someone who has repeatedly lied, repeatedly silenced others for misinformation that have categorical proof and someone who has openly posted a mod level comment condoning the bullying of instances provided they are under a certain number of users. Lemmy.world admins are willing to give admin level control and abilities to a user but are unwilling to force him to take the accountability of an admin.
A defederation vote must be held immediately with the Flotilla. Lemmy.world has surpassed bad acting at this stage and have proven they have no active administration that can be trusted to follow their own Terms of Service.
Kaplan stated about Anarchist.nexus that there is "there is no sufficient moderation of violence on communities there". Yet, Lemmy.world has no sufficient moderation of its admins or mods at all.
