No worries! Happens to the best of us. A lot of people have had this happen lately. I've had my comments post multiple times accidentally the past few weeks and I have to go back and delete them or sometimes I just leave them. I've also had problems with my votes not going through.

Your multiple posts still didn't clog my feed as much as some of the serial resteemers here...there's nothing wrong with resteeming but some people do it dozens of times per day (I won't mention any names).
