The misuse of selfupvote is one of the major problems here. Some users dont want to be in a community and share everything with others, but instead working for themselves alone. Upvoting their own comments and leaving. And it is not only about whales, but also new minnows who dont understand the right strategy to survive here. Instead of making friends and growing here together, they prefer to be alone, what makes them look like spammers and couldnt go any step further.
