So I have recently discovered that Blogger is retroactively marking random comments all willy-nilly as Spam - including MY OWN comments on MY OWN blog.
Most recent dicovery was today. I noticed a comment had been marked as Spam (it happened today because the Spam folder was empty yesterday) on my Stacking the Shelves #219 post. I went to the post and sure enough, Cindy's comment was no longer there - but my reply to her was. I went back to the Spam folder and marked her comment as NOT SPAM, then refreshed the post's page. Her comment showed up once again, with my reply.
Seriously Blogger, get your shit together.
And while you're at it, give us spell checker back - one that is actually functional and useful and accurate this time.
