Are you zapping yourself from another custodial wallet?
Hmmm, yeah, this is an argument for clients to take a rake on zaps. I might have zapped myself on StackerNews once as a Sybil. 👀
LN tips with comments are excellent signals.
Zaps are useful as quick tips.
Retweets are good signals.
Likes are good feedback mechanisms for small-medium accounts and reduce the 'yups' in the feed.
All of these can be gamed except for the LN tips.
