Policy does not prohibit users, whether registered or unregistered, from removing comments from
their own talk pages, although
archiving is preferred. If a user removes material from their talk page, it is normally taken to mean that the user
has read and
is aware of its contents. There is no need to keep them on display, and usually users should not be forced to do so. It is often best to simply let the matter rest if the issues stop. If they do not, or they recur, then any record of past warnings and discussions can be found in the
page history if ever needed, and these
diffs are just as good evidence of previous matters.
For a list of exceptions, see
Wikipedia:User pages § Removal of comments, notices, and warnings. If you believe it is appropriate to restore this content, please click "Publish changes" or "rollback" again, and
report this error.
