Ok I might not understand this, so if someone could point me to information I would appreciate it, but how exactly does a reply harm anyone? I saw it as a means of saying something without having to dedicate actual resources to it. It isn't about being "selfish", it just seems odd that you would think "Thanks"is trash, but "You are welcome" extremely relevant contributions. Isn't the entire point of steemit to vote on "contributions", as in, actual helpful comments? Not every niceness thrown your way?

I mean, it is fine, I am not particularly concerned, I will just say "Thank you!" instead so I don't get instantly flagged.
