Wikidata:Deceased editors/Guidelines
Consider archiving any unseemly disputes, warnings or deletion notices. {{Deceased Wikidata editor}} may be placed at the top of talk pages, and at the end of long talk pages.
Editors who choose to do so may leave tasteful condolence notices on talk pages, by editing in the usual manner.
On the account edit
The user rights of deceased editors should be removed. User rights to be removed primarily include administrator, rollback, Checkuser, Oversight, and Bureaucrat rights. As rights of Checkuser, Oversight and Bureaucrat cannot be removed locally, a request to remove those should be posted on m:Steward requests/Permissions#Removal of access. If rights are removed, a note should be made about the rights the user held in their editing tenure.
By default, constructively contributing Wikidata editors should be honoured with a listing at WD:RIP.
If the colleagues of an editor feel moved to do so, they may create a memorial page to honour the deceased, as long as the family has not objected and the user did not object to it prior to their death. Entries to the memorial page should be as tasteful as possible; edits that fail to be tasteful will be removed. Memorial pages are not mandatory; they are created by the community for the community rather than as a requirement.
Also edit
Delete the user's subscription to automated newsletters such as signpost, project updates, etc.
Check to see if the user was active on sister projects, and leave notes on their 'village pumps' or equivalent, or at the relevant embassy, if so.
If the user was notable, check to see if there was an item about them, and update it and any Wikipedia articles, as appropriate.
