I don't get them too often, but I have grown weary of spammers, bots, and people who behave like bots. If I can tell it's a copy/paste response, I generally just ignore it. I've only ever flagged one spammer because he actually posted nothing but a link to one of his posts that had 0% to do with the post he commented on. Upon further inspection, I found that he had posted the same link to about 20+ posts back to back.
I think a lot of people miss the point when they read about how to gain followers on Steemit. Many people are told "comment for exposure!" But they don't take the time to understand that there has to be something of relevant substance in their comment, or there won't be a real connection (which is what I think actually drives users here to build a real audience).
Great article. I really appreciate more established users letting some of the newer Steemians know that people can tell when they're fishing for upvotes.
