I will suggest to create a list of permabanned user for copy/pasting and moderators giving track that which post of that thread they have processed. This will help in reporting as we can easily check whether user is already banned or reported by other but pending review by moderator so no need to take action or re-report.
A Rank "Banned" has been suggested before (by me and other people). That would be the fastest way to know an account is banned already, and doesn't need further attention.
Any particular reason was given for not implementing the suggestion? Actually I am not in mission to catch copy-paster , but they are so widespread in forum that I automatically find them. A Banned list is not only useful for people reporting them, but it will cause fear in copy-paster too. When they see that so many user are Permabanned , they will automatically mend their ways.
Chances are the Mod who handles the ticket can't ban the user. Most Mods can only nuke Newbies. The post will get deleted, but the user won't get banned.
Can't send a message to the person who is able to ban that user?
Have you tried that? My personal experience is that Mods/Admin rarely reply to PM.
