I just don't have time for it. I'm running for office, and I'm trying to make the Recall a success.
I don't have time to waste going through 20-30 nutty posts a day...most of which are slamming me or critical in some way. I don't mind the criticism, but I don't need to waste any more time on it.
Maybe I'll enable it at some time in the future, but right now I am too busy.
