A lot of Twitter spam can easily be combated with more options under "who can reply/retweet", such as: only paid Twitter Blue subscribers, only followers, only verified users (especially with more ways to get verification), only users with verified phone numbers, etc. Right now tweets are either completely public, completely private, or close-friends-only. If Twitter wants to easily solve the moderation problem; let people have moderation tools over replies to their tweets. Then allow those restrictions as filters on the timeline, who can follow, who can DM, or as visibility for their own tweets, which can probably also be paid features.
