The "Global user contributions" tool does not show account actions like blocking, protection, patrolling, reviewing, tagging and thanking. It may be helpful in some situations to have a comprehensive global log that encompasses all publicly logged actions.

I have accidentally dropped my Huggle bot password (instead of a prewritten message) in a Wikidata revert edit summary. Theoretically, an attacker filtering Special:RecentChanges for bot passwords could have automatically abused my account for a period of about 10 seconds. There seems to be no way for me to comprehensively check whether that has happened on any of the ~1000 wikis. The abuse scenario is not extremely unlikely due to the standardized composition of bot passwords and the API access that comes with them.
Please create a global account action log that fixes this lack of information. Alternatively, or additionally if needed, please manually run a database query for my account (2019-04-26T19:55:25).
