When a users profile is no longer existing, there was some content left on site - with some confusing display errors.
On the wall, deleted users comments are displayed as Anonymous.. Which is not so bad, but better not show (for this site anyway).
The real problem, is that "Anonymous" avatar will display the currently logged in and visiting users avatar instead..
(We got emails like: Someone has stolen my pictures..)
I post this in forum, cause I'm pretty sure it could be fixed already (existing cron job and/or change so anonymous/deleteduser posts are not shown/deleted.
I use this query in a cron script, to remove comments without an owner:
DELETE FROM bx_wall_events
WHERE object_id NOT IN (
SELECT ID
FROM Profiles
)
AND type = 'wall_common_text'
Please comment if this is already fixed, or if it has/needs a ticket.
Cheers
