Want election integrity? Great!
Ban ALL election advertising on social media. Leave social media to be SOCIAL media. If a public official has a page where they interact directly with the public, fine. If it is nothing but more advertising and propaganda, it should be banned.
Support ALL elections funded by taxes, bottom to top. Eliminate campaign PACs completely. Equal funding for the top 3–4 parties, NOT two. Open debates, open primaries in all states. Paper trail, fully open to audit for all elections. Eliminate superdelegates.
Any and all claims by elected officials or the media of interference without PUBLICLY verifiable hard evidence should be legally considered libel and should be prosecuted to the full extent of the law.
Then we can work on making lobbying a criminal offense with mandatory prison time for lobbyist and lobbied official.
What you are truly proposing is publicly endorsed censorship. Just one step further into fascism.
