I don't game it knowingly. There are a handful of people I zap and who zap back frequently, which likely inflates any meaningful metric...hmm. I'm thinking about it now...
I guess I'd be interested in knowing net zaps, and distinct npubs zapped, and I don't really care if the numbers are gamed. Most don't game it, I don't imagine, and I think I'd pick up on it if they did. I just don't like the feeling of zapping people who themselves don't really zap. It's petty, but I guess I am petty 🤷♂️
