Well the rudeness is a side effect of a flawed system. To have “attachment management” that doesn’t allow you to manage your attachements is frustrating. I wouldn’t have been rude if I wasn’t frustrated.
This has obviously come up more than once, and yet the problem still exists. Someone should try and find a better solution. Notify users that the thread will be locking soon and they need to manage their attachments, don’t prevent the deletion of attachments because a thread is locked, give users an option to have attachments removed prior to the autolocking.
