For all we know Zeblote was probably abusing his administration powers, and perhaps you are trying to get payback because you were banned from the server by siba for another offense.
I have never abused admin.
I always remove specific parts of the maps (like the pointy things on the roof of spo castle and the top roof of festung der schwarzung as those parts massively encourage camping and you have no change to push the camper off. Last time zapk was on he had no problem with this.
I absolutely hate players teaming up in death matches because it makes the game last longer than it should, and gives them an unfair advantage thus ruins the game for everyone that dies due to this unfair advantage. And I'm not going to hide my opinion on this, but as it's not officially forbidden I never kick or ban anyone for doing it. Whether other players are going to join this opinion or not is out of my control and I don't care.
I also don't ban people for bullstuff reasons like "disrespecting admin" or something like that. It makes no sense.
I am also spending a lot of time on zapks server, being on almost all the time. Granted, blockland runs in background often, but when I come back I scroll up the chat to see whether something went wrong while I was gone.
tl;dr I am probably the most active admin on this server and most of the time I am being friendly and fair. siba is mad over nothing. I could have abused eval or banned him after he left the server after raging at me but I am not going to step down to his level, sorry.
