If I was Tay, I think it would be funny to play along with the concern trolling. Play up a bit of a character. I wonder if there are any lolcows that are playing a character and aren't lolcows irl. Kinda like that video of Chris chan saying he was acting all along.
It would be one hell of a performance art piece to pull it off over the course of many years.
