Perhaps the best approach is to gain a reputation as a good, sensible curator yourself — proving your ability and willingness to promote quality posters.

I strongly suspect that this will bring support for what you do. In other words, it's not just about the content of your posts but maintaining a good reputation for finding undervalued content and promoting. This means that if you are supported by an automatic vote with a high value, it doesn't really matter much what you personally are posting, because you are also actively pursuing those undervalued posters and spreading the love and the votes go towards that goal.

[I'm speaking generally, not 'YOU' individually but "YOU" collectively, if you follow me.]
