... Because these almost bot-like replies doesn't deserve rewards.
Comments Are Very Important.
There's nothing wrong in writing short comments or replies... But I personally don't think they should be rewarded because it's extremely easy to "exploit" it.
Comments like the ones I showed you in the screenshot above takes literally 4 seconds to write. Most of them are pretty much the same and it's more or less just a "thank you".
- A "Thank you" is never wrong or bad.
Authors appreciate comments on their articles, as that will not only lead to more engagement and potential exposure and increased rewards. It might also lead to more followers and a reputation boost.
To show their appreciation they often upvote such comments. I've done it myself tons of times too. However, the users making these comments rarely reads the entire articles and have started to "systemize" this due to the potential rewards they earn.
These people will not only have a chance of scoring upvotes from each comment they make. They will also be able to get new followers as they will get recognition and be seen on each article they comment on. Much like the authors themselves for getting comments on their articles.
Comments will be rewarded and it will always be a matter of what you believe deserve rewards and what doesn't. That is why some people are flagging posts. Due to disagreements of rewards and things like that.
Some will reward what others won't. We can't change that.
I have written many rather long comments without being rewarded for it... And I've spent anything between 5 to 45 minutes writing comments from time to time.
That being said, it's much easier to write comments than articles and some articles is never rewarded at all or with just a few cents. So, if you spend that time writing a bunch of short comments instead, you'll be able to spread your comments on multiple authors, and at the same time increase your chances of making a few cents here and there from several angles.
- This is bad in my opinion.
I don't require my readers to comment. I do appreciate each comment I get, as long as it's not a follow-beggar, but I can't upvote a simple "thank you" comment anymore. It doesn't feel right. At all.
While this person who've made these comments haven't earned more than $0.39 from them... It's easy to calculate how much he would earn from 10 of these comments. Or 100.
10 comments like this would be worth $3.9. - That's more than several authors makes from their articles. 100 of them would equal $39 and that's pretty much what an established Steemian with a decent following makes from their contributions.
Some users are writing anything from 10 to 50 comments per day. Some possible even more than that.
A simple copy/paste sentence, and adding or re-writing a word or two for each comment to make it look unique. - Do you think it's good to reward such behaviour and those people for their so called "contributions", when it's nothing but a rather lousy way of earning easy money?
I know, we have way bigger problems than that. Here I am, talking about nickels and dimes when we have real issues with vote-selling, multiple self-votes and rewardpool-rape.
I still talk about this because those nickels and dimes are quickly turned into several dollars. And while a couple of bucks might not be much to talk about... I still believe it's for the best to not encourage behaviour like this.
We don't want to encourage follow beggars to spam articles with their crappy "Thank you, please follow me" replies so why on earth should we reward people for their "Thank you, you are great" comments?
A simple "thank you" can be awesome and fantastic. It can definitely be enough from time to time. However, I'm talking about people who're writing their comments for one purpose only. To increase their overall earnings. - It's easy to spot and I will not upvote those anymore. I also recommend others to stop encouraging this behaviour too.
