Here's a handy guide for you:
1) Is the thread started by HB&B?
yes - go to question 2
no - you're safe
2) Is there a link in the post?
yes - it's his blog/"article" - you're better off avoiding it
no - close the thread and never go back. You're just giving him the attention he craves
Perhaps you can create some kind of decision tree to cover all HB&B based scenarios
