i also spotted 4-5 bots (accounts with names same, but differing in digits - like nextgen-11 nextgen13 ) who also downvoted, so you're not alone.
eventually all the authors going to be found, isn t this bvious? i d upvote your comment if it d show us all who s the author.
however - it s 5 minute task in 2016 to google where photo comes from (which year google bought tineye?) - yet you re downvoting.
coupe of weeks ago, we realised we do not need emails base :)
not for that email campaigns are wrong - but because all the people some or other way are on the radars already.
