Let's take this spam-comment for example: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206544#c6
I've tried to remove it, or mark it as spam, or report originator as spammer but I could not make it.
All that I've found is "Spam" link at the header that leads to https://bugs.freebsd.org/bugzilla/page.cgi?id=searchspam.html
Its form finds noted commend searching for spammer's email but proposes "to block the user and delete all bug reports". It is not clear if it really would remove the PR or just a comment. It is not clear if it would block spammer's account or reporter's.
There should be a way for any @FreeBSD.Org Bugzilla account to mark/block distinct spam-comment and its originator.
I've had some thoughts around anti-spam improvements recently. I'll collate my notes and add them here
Long time passed and still no solution. Fresh example: email@example.com is spamming in multiple our Bugzilla comments just now and I see no way to block or report it.
(In reply to Eugene Grosbein from comment #2)
The mentioned link is the current solution for this problem. The list of commented/created issues is supposed to be used to get the overall user's activity to check if they are a spammer or not.
The block button does block user as a spammer and marks all issues/comments as spam. This means that although in the database it's still the original text on web UI it's visible as "MARKED AS SPAM". This is to prevent users from deleting stuff permanently by accident.
This functionality is available to all users with @FreeBSD.org email
Where a bug is MARKED AS SPAM, does Bugzilla also allow edition of the HTML title?
Also, obscurely, if a report is listed amongst search results, the listing shows the original summary line. <https://bugs.freebsd.org/bugzilla/buglist.cgi?bug_id=257805&bug_id_type=anyexact&list_id=531225&query_format=advanced>, for example.
