I don't now what to say, except I am blown away that you went and examined each one even though there was nothing on the line in way of a reward or bounty since I had cancelled the contest.
I also believe you caught them all.
The biggest mistake of all that I made was 2/2/18. I did make a post that day and it did not have the date nor did it have my signature photo for the daily dose, the salt & peppers packs. That day was a post that was part of the #steemusa "state wars" competition that was taking place and it was a food fight. Texas won that fight hands down with slow smoked BBQ.
Thanks for taking the time to review them all and verify that I actually did pretty well at holding down the mistakes, for 400 posts that isn't a bad record in my opinion.
