I always think twice when is about to downzap. Why? Because I have to measure exactly the impact of that downzap or the other way around is to reply with a meme.

Let's say I downzap with 100 sats. That downzap will not affect too much if others will not downzap too. That means my sats were thrown away for nothing.

But if I post a meme, as reply, on one side, the sats used to post goes to the same SN pool, but if somebody like that meme, I can get it back or even more.

So downzapping is not so effective, I test it few times with various amounts. Is not easy to outlaw totally a post/comment. And I think is a good protection against brigadeering downzapping.

So yes, think twice and only specific really bad comments to downzap. Don't downzap with your feelings, but with your brain.
