The most common reason is that you may be doing too well for us to upvote your content, although it's relative with prices and these markets, of course, and there are some outliers that we try to hammer down and remind curators that they're out of our scope, etc. But yeah, usually the best way to overcome that is to target communities we focus on and go a bit beyond your effort in content so we'd still want to upvote it even if you generally receive okay upvotes.
