Can you blame them? They keep getting away with it. You're probably one of the few people to take a stand. There are countless others not doing their part. At the beginning, I remember a guy who would just post "I like your post" on every single post I made. I guess for whatever reason, I just gave him an upvote. After about 20 times, I had to stop giving him an upvote, because like you say, it just began to annoy the shit out of me. Nice post (sincerely). Hopefully it brings some awareness to the issue.
