I think the idea of one physical person one identity is doomed, only the tyrannical still want this. Have a dozen nyms at any time all for different interests or facets of your identity. Kill them and create new ones regularly. Use AI to run a couple that intentionally poison the well for data scrapers. Never use your government ID anywhere but with the government.

Dating scraping won't go away unless we make it useless. Data wants to be free and someone will always try to use free data against you.
