I wouldn't consider "spamming" as an appropriate word as each of my responses is tailor-made to the situation.
I have acquired 508 followers, mostly because of my responses. You might not like them, but others do.
Despite my 508 followers, my articles seldom go past 50 views. It seems the best way to be popular on Medium is to write at least one good article a day. I just don't have the time resources for that endeavor. Nor do I want to write about the same thing ever day, just in different words.
I thought Medium was too big for my responses to get repeated exposure. It seems you have proven this hypothesis wrong.
