In git-plugin, the documentation for the "Excluded Users" field says:

Each exclusion uses literal pattern matching, and must be separated by a new line.

It is not clear what "literal pattern matching" means. For example, if I want to match a user called "renovate[bot]", it is difficult to determine what value I should put in the field. It is not clear if wildcards of any kind can be used.

The documentation:

• in the Plugin UI
• and in https://plugins.jenkins.io/git/

should be updated to clarify.
