I agree, you want an active following. But, there is a bright side of this too, but I'm not talking about sub4sub youtubers but sub4sub websites. If you're a small youtuber and find it hard to get views even though you make good content, it may be because people don't care about videos with few views or channels with few subscribers. I can see why people do it, but you shouldn't do it as a habit, only if you're very new and need a little help.
