Duplicate Illegitimate Posts

Hi.  It was noted in a recent article by Art Frentzel that there are multiple duplicate posts attributed to me that occurred on July 27, 2017. I have only posted comments for ATRS and OESX articles.  Would you please investigate how/why this happened and delete the posts not attached to ATRS and OESX.  Is it possible there was a system problem that day at SA or I was hacked.  Other than this day everything else looks correct.  Thanks.
