Yikes.
Quora is becoming more like Facebook in its mysterious deletion of accounts.
I only caught the one below because of email notifications. This used to be "Christopher Smallwood" who replied to one of my comments. Now, he's just a meaningless string of numbers; I imagine all of his other posts have been deleted as well.
Thank god for these email notifications, or I would never know about this.
@freemo It is a possibility, I suppose, but I have seen other comments deleted by Quora when the author did not intend it.
