Yes, that's what I instinctly felt was the right way to comment from the first day I started in Steemit less than a month ago. I saw those kind of spammy comments all around since I joined and I never felt that those who write them actually read the posts they were spamming, but were only looking for upvotes for their comments. When I did visit some of the blogs of those spammers, I didn't see any valuable content. People sometimes forget that they are building their reputations, whether in a positive or negative way, with each comment, post and reply they make. Thanks for reinforcing my understanding of this commenting issue.
