my counter argument as a curator is that i'd rather spend it on other people, especially if I already do well enough on my posts from my own judgement

but generally agree, as long as you don't overdo it, it's not the worst thing in the world - some disagree with that and that's fine, it's about the intention at the end of the day. Are you doing it just to farm or just to fairly grow your stake with what you feel is deserving of your own vote.
