By default it's first-name only when copying from social media (Facebook, Google Plus) and full name when copying from forums (LessWrong, EA Forum), though I have it always use my full name for clarity. While everything I copy over is already world-readable without an account, some people don't want their comments copied (let me know if that includes you!), in which case I show something like:

It's a little fragile, though, and about a year after I last fixed Facebook comment inclusion it broke again. And Google Plus was turned off, so I couldn't pull comments from there either. And the EA Forum and LessWrong migrated to new software that didn't support the old (and not very good) rss-based system. And my adapters for Hacker News and Reddit broke too.

I've now gotten the main four working again, though it's not quite the same as before:

• Google Plus, being shut down, just serves a frozen archive as of my last backup.

• The EA Forum and LessWrong use the GraphQL API and pull comments as needed, so crossposting is very fast.

• I have new code for Facebook that runs selenium while logged out to build an archive, and I'll figure out some system for updating it at some point. Crossposting is very slow, like ~weeks.

At some point I may get Reddit and HN fixed, but I don't crosspost to them very often so it's not much of a priority.
