Indef block 
I believe you got a bum deal and should not give up. The admin cited a preponderance of evidence without stating at all what that evidence was. The CU is not mentioned regarding you and Minusjason, so that is not it, otherwise it would have been mentioned. Admins can be a high handed bunch, and they most likely blocked you for your incivility. They will not admit to it, but dislike of your vocal objections hardly will make any of them feel obliged. I would appeal and ask for a detailing of what evidence was regarded as compelling. If it's the similarities in edits, then their argument is weak, very weak. It is reasonable to assume that two different editors would agree and make similar edits. Unfortunately, there is a star chamber quality, meaning a huge lack of transparency involved, to how these judgements are issued, and they will not feel an obligation to explain themselves, and no admin can demand a  better rational for how the block was decided. If you appeal, you will need to deal with the fact finding process, and leave out how idiotic admins can be at times, however obvious this may seem.
