"Why I review Products? I had a very bad habit of commenting my opinion on the posts of Hacker News's Show HN section. Some product makers liked my comments and appreciated it while others thrashed me for the truth."

I mean I can look through the author's HN comment history. There were only 4 comments on Show HN posts. All of them one sentence or less and all very positive. Can't find a single downvoted comment or negative reply to a comment.
