It's true that a lot of this things are not technical problems. But you can create systems which amplify such behaviour and systems which avoid such behaviour in many ways. Similar you can design systems which enable fraud, especially social-engineering based ones and you can build systems which makes fraud harder. And one thing which anyone having run any kind of discussion platform weather in the internet or physically knows is you need proper and strict moderation or things will go down hill. Twitter always had been doing a soso job. And as far as I can tell things will get worse, not better with how Musks is approaching things as he seem to either not understand the problems or doesn't care.
