I'm faced with a user who picks a small element of my question, posts an "answer" as a comment and (likely) down votes, and sometimes will vote to close as duplicate of something which does not answer my actual question but may address that small element cited in the comment.
I feel that these are at a minimum "false flags" and disruptive, and I feel that there has been a pattern of this.
There are two examples below. Should I start flagging these?
For the first one I've responded by editing the question to explain why the proposed duplicate isn't even close and left two polite comments. The next day the same thing was done in the second question, so I don't know how to respond differently.
