except these people do go to other places and then people tell ISPs and the such to block those websites...see 8chan.

Look at the controversy over platforms like parler and gab as well.

This is why I think the ultimate solution is to have platforms that are fully encrypted, anonymized (TOR) and decentralized. This is the only way to ensure people can exercise their freedom of speech without harassment. Basic implementations have already been built, bitmessage, for example but that technology needs to be expanded into more of a reddit-like website. Make posters/comments/upvotes burn CPU cycles to participate and pay rewards to the people hosting/mining.
