[tag:google] (the manufacturer meta tag, see [Manufacturer & Company tags are back. Again](https://meta.superuser.com/questions/8402/manufacturer-company-tags-are-back-again)), was cleaned up a little over a year ago.  It stayed dead for almost a year, but starting in July of this year, it began showing up again and we already have 41 new questions.  Is this tag a sufficiently large pain in the butt to blacklist?

Update: It was cleaned up again, and just showed up again.  Can we PLEASE blacklist this sucker?
