The manager has not "refused."I spoke to the manager a lot last spring when this started happening. He refused to put a limit on the number of threads a new user could start the first day they create an account.
The manager deserves wrath. And it's whiskey season.
If you're so certain that this could just be done easily, explain how. I'm happy to modify any XenForo2 setting that you can find that will accomplish this task.
