Oh don't worry. The big delegators all know what they do support. The downvote trails are even bigger, and growing.
The community is finally standing up against selling and trading votes. Only those who want to keep using the reward pool for their personal gains keep complaining. Those do not support the community as a whole, and we're better off without them.
Every steem that doesn't go towards self rewarders is available again for the rest of the users. That's why we see a lot of small authors earn more these days than before the free downvotes were introduced. This will allow the community to grow, and everyone who participates will profit.
