I did ignore the terrible trio when they started up again, but HRG was worse than a troll, he had an undisclosed conflict of interest and was trying to push his illogical views (sprinked with truisms) down our throats to further his own interests. I thought it was worth it to call him out. So when his "friends" the terrible trio chimed in it didn't take long for the penny to drop and realise they were all the same person.
Not sure who the next one will be, they may already be lurking ...
