More than irritating, that person's comments suggest some real prejudice and are strongly defamatory. If someone comes in brand new and tries to make a name for himself by tearing down others who have proven themselves and who he knows nothing about, questioning whether this member speaks English and uses cheap labor to help with her posts, then that behavior doesn't belong here. @sweetsssj is one of the hardest working people on Steemit and I have had numerous conversations with her in English over a period of many months. Believe me, I don't use that downvote power lightly and only do so very, very infrequently when there is a clear cut case. Beyond that, I fully agree with you we need to continue discussing how best to handle trolls without anyone misusing their power.

Fortunately, there are checks and balances even now: I am being watched and anyone who disagrees with my actions has time to review the facts and show me if I have voted mistakenly. If so, my votes can be removed or countered by others in the community for several days still. In this case, I don't see that happening because the troll's comments were way beyond my understanding of the standards that this community has shown to uphold to prevent the type of harassment they displayed.
