I'm seeing the same warning message, and although I haven't posted anything, I have upvoted several posts in the past hour and my upvotes are not listed on Steemd but do appear on Steemstats. I upvoted your Storm Front at the Reservoir post, which according to Steemstats was posted half an hour ago and I upvoted a few minutes later, but I don't see the post or my upvote on Steemd
