I have recently noticed that a specific user has been trying to promote their unanswered question by finding similar questions to theirs and posting a link to their question in the comments on one of the answers, asking the user that answered to have a look at their question, i.e.:
"I see you have answered a question on this topic, can you look at my own question on a similar topic and also answer it?"
Is this appropriate?
This is not the first time I have seen this user use this tactic. They have 6 near identical comments on specific answers asking the user who answered to look at their question. I was alerted to this as I was one of the people contacted. As I said, I have noticed this user employ a similar method when they had previous questions, though I am unsure if they then went back and deleted their comments if and when they got an answer.
It is my understanding that comments should be about whatever question or answer the comment box is under. To me this type of tactic almost comes across as spam and a misuse of what I thought comments were for.
I did suggest to the user that they should not use comments for this purpose and they were happy to remove their comment, but I then noticed all their other comments. I thought it best to clarify what the policy is on this and if necessary, what action I should take.
