On the chance that additional supporting voices might help, I'm also looking forward to something from Wordfence that would prevent fake sign-ups. Those guys are driving me nuts, as I'm having to ban them manually...ever day.
It's gotten so annoying that I'm looking for an additional (and hopefully temporary plugin that can address the problem in the meantime. I already know that whatever I find, you guys will ultimately do it better..>:)
Thanks,
Steve
