Users removing warnings from thier talk pages 

I recently came accross your comment on User_talk:HiImPhil regarding his removal of warnings from his talk page. Warning removal, while frowned upon, is not prohibited by any official policy. See WP:USER and Wikipedia:Centralized_discussion/Removing_warnings. While it is certainly reasonable to ask users not to remove warnings, it is not a good idea to suggest that they are not allowed to. While the warning removal does make fighting vandalism a bit slower, there is not a consesus to prohibit it. Thanks
