It has happened several times now to Trusted Users that they have been banned for the reason of:
More than one person has expressed that they would not like to work with the user in questions.
This is one of the strangest reasons given on a site with such huge volume and risk of confrontation as Stack Overflow. Anyone actively participating sure confirms that confrontation does happen on a daily basis and so likes and dislikes are born.
In fact, if one fundamentally disagrees with the moderator team, there is likely more than five to ten people who would not like to work with that user then. That may be for instance because the user has vastly different goals with the Stack Overflow site than the moderators. Thereby, one may already become a very inconvenient and hence ban-worthy user.
It does not need to be reiterated that Stack Overflow is mostly a game rather than a quality knowledgebase. This causes further nonsensical debate, sadly. Therefore, there are many people who would be banned based on this premise, especially among the moderators who get into lots of confrontational cases.
