Frank has made quite a mess in this thread. But he has also kept it in this tread.
If you decide to lock it you should also take into consideration how he´d react when he sees his favorite hole for rambling about his ideas gets sealed. Will he try to make a drama and start a new thread? Will he move to one of his other threads? At worst he could start spewing his teachings into places where they don´t belong.
This shouldn’t stop you from handing down a verdict, though. Regardless of the judgment this thread will receive, it has been postponed for long enough already.
