You are not alone on that one! There is a lot of use here thinking the same way. What bugs me that those people think it actually works! And lots of them do say they upvoted, but they actually didn't.
When I get comment like that I just reply "Thank you". Ant begging for upvote and follow and checking what they post doesn't work for me. And never will.
It is much more effective if I get a meaningful reply, or something funny and catchy. Then I will ALWAYS check the person profile.
That's the way I feel about comments. I don't mind if its a short 'Great Job' but I do like some body in the message. If something was off in my post, let me know. If it was entertaining, let me know. I love to hear from my fellow bloggers and I comment others frequently. It is what makes STEEMIT the better choice for blogging. That sense of community.
