Totally agree with you! I am the same way, so to say that on one post I comment "keep it up" doesn't mean that I'm just doing it for the upvotes or to get followers because I commented, I just truly mean it even if it's short. I'm not going to write a super long comment on everything I like, although a lot of the times I do lol, because I just wouldn't have the time. What I don't like is when people simply ask if I could follow and they don't even comment anything about what I posted on. :/
