What's funny is, since sub for sub is something everyone knows on YouTube, there are people on YouTube that spam "great video," to noobs and get then noobs to follow them. YouTube built a filter for it, but many people don't take the time to learn how to use the filters."
I think on some articles, "great post," might be excusable. If someone just posts a picture with no words, should they get more than just one line comments? This is a question I struggle with.
