Well, I believe things with serious consequences like banning someone permanently - should indeed be presented clearly. Exactly because I know some organisations like to shield themself from criticism, by having a intransparent process.
That's right. Often due process is skipped even if the blocks turn out to be errors or collateral damages later. It's not going to be 100% perfect at all because stylometries can be obfuscated (see https://ieeexplore.ieee.org/document/7345380/) and there are tools like VNC and residential proxy applications to evade IP-based tracing and detection.
You may believe your position is: > should indeed be presented clearly. Exactly because I know some organisations like to shield themself from criticism, by having a intransparent process
but
> Because it is extremely hard to figure out what is going on. Lots of mysterious abbreviations. Unclear timeline.
> But in a real court, I can see the verdict and the laws that were broken. All in complicated, but readable english. Which makes it clear (usually). But in wikipedia to understand a indefinite ban, I have to understand global wiki community dynamics first?
your position aligns with someone who desires decision with serious consequences to be easy to understand.
It's pretty straightforward but nothing on Wikipedia is really black-and-white. Most decisions are made through a consensus process. It's really quite different from what most people are used to.
A good place to start for information about how user blocking is done would be the following links:
https://en.wikipedia.org/wiki/Wikipedia:Policies_and_guideli... https://en.wikipedia.org/wiki/Wikipedia:Blocking_policy https://en.wikipedia.org/wiki/Wikipedia:Sockpuppetry
In this case I think that a sock puppet account can be trivially blocked without much process as long as it can be proved that it is operated by someone who is already blocked for some violation. The sock puppet is an attempt at evading the block that was placed on that user's other account.
