I do not know either of them. I watch.
We do not hesitate to complete here a little information.
To be able to manage the deletion, or, to hide the logs totally, would be a plus for this UserMerge extension.
Thank you for participating in the discussion so quickly.
I had already tested Logrestriction but I was not able to get what I wanted, to properly hide UserMerge logs, to non-connected users and to single users.
Test 1 # KO
An intermediate solution would be to disable the extension once the merges and deletions have been made.
If the extension is disabled, "log-name-usermerge" is displayed instead of "User Account Merge Log".
A single line will then be displayed in the last changes since Mediawiki: "18:25 (⧼log-name-usermerge⧽). [Zer00CooL (46 ×)]"
Even so, the pages I post on another site with an RSS feed continue to serve the information, a line for each profile that has been merge and deleted.
Disabling the extension is therefore useless. I leave the extension enabled.
Test 2 # KO
# Do not display the UserMerge logs.
$ wgLogRestrictions = ['usermerge' => 'bureaucrat'];
# Bug 1
# Works in part since Special: Journal
The logs are not displayed.
The logs are not displayed either with my connected bureaucrat user.
# Bug 2
# Error from Special page: Journal / usermerge
You can not ⧼action-bureaucrat⧽, for the following reason:
You do not have sufficient rights to perform the requested action.
Test 3 # KO
Another alternative would be to use Lockdown but still it does not seem to work.
I am not on options to indicate, I try "usermerge" to forbid to "user" but the users always have access to the information of journaling, in particular, on "Latest modifications".
I found how to hide all the "last changes" but this is not the purpose of hiding all the changes, only the merge and deletion of user account.

I may not use the right configurations, I do not know how to move on now.

# TODO
I would then search the database for "deleted the user account" or "log-name-usermerge" or "usermerge".
See if it is possible to delete these kind of entries directly from the database.
# I think it would have been better to use the CleanMediawiki.sh script to delete users. I did not test it. https://github.com/ZerooCool/cleanmediawiki
