I just set up Anubis today. Specifically I'm only testing it for Lemmy-ui, and it seems to work fine.
It looks like the distributed waves that keep bringing the service down hit exclusively our lemmy-ui subdomain, so maybe non-SSR photon is also a good defense, heh.
If another instance started knowingly federating us ads, or fake content, I'd hit that defederate button very quick.
You forgot the biggest concern that people have.
Remember that Meta's strategy has always been to buy out or kill competitors before they grow too big. This time, when the competitor is immune to normal methods, they're all so friendly and cooperative. Why the complete 180, did they suddenly turn good?

Is your mind changed?
I don't think it should be a problem, but I'm not that sure either. Lemmy.fedi.zutto.fi also runs it and that's just a normal lemmy-ui installation. I think Zutto simply forwarded all traffic to Anubis and then fixed federation. There was some discussion and config shared in sopuli's finnish matrix room.
