This is the quote from that guy's emails:
##### BEGIN QUOTE ##### 1/8 of 1% of all submissions have not been validated...
Yesterday we saw 253,081 Votes. Of those votes only 288 were not validated. Of 250k emails going out a day and only ending up with 288 not validated I think were doing pretty good. The pure volume is going to cause some sites to mark us as spam. ##### END QUOTE #####
The rest of that post is me.
