Did pg give a reason for not wanting to remove the account or did he ever write about why he wouldn't delete accounts? I have my guesses but I'm curious what his specific reasons would be.
I asked if he could either remove my account or comments. He said that the comments are part of other people's conversations, so he didn't want to remove all of them (later he asked if I had some specific comments I wanted to remove, and what were my reasons to want to remove all of them). By then I realized he was right.
Of course there could be numerous curatorial reasons, but that first one would seem to be a deal-breaker regardless.
