It's good to note it's a tradeoff, with WoT score set to 1, all the people who you and your follows don't follow are hidden along with spammers.
With it set to 0 it hides people with -1 WoT score, which, I believe, are people who the people you follow have muted or . Which is better than nothing but still a cat and mouse game, there will always be more spam accounts than muting. #nostr #WoT
