I don't have a specific solution for you, but I also run a domain with some thousands of subdomains and is always a fight to not be banned from Google, Meta, internet operators etc. Sometimes is enough one bad actor under one of your subdomains to have a full ban on the whole domain.

What I suggest is for your and your clients to contact Meta through the Business Center support. Their support for paying clients is much better. I would also recommend you become a Meta Business Partner if Facebook/Instagram is important for your SaaS.

If you're running independent subdomains where a bad actor on one should not affect the reputation of the rest, you probably should add your domain to the public suffix list: https://publicsuffix.org

Thanks, I didn't know about that list. I'll try that!

Note that adding your domain to the PSL changes how browsers interact with it, so don't do it lightly. In particular, no more cookies for the parent domain.

It would really be a shame if something was to happen to your domain in our ecosystem because you're not a paying partner.

They're mobsters.

You think you should get everything for free or something?

You think Facebook isn't getting something out of allowing users to sign into other sites through them?

[dymk]

You think the site isn't getting something out of allowing users to click a social media button to sign in?

[yellowapple]

It's almost as if the button is mutually beneficial and that only a greedy moron would threaten to break it unless paid yet more money.

Yes

Perhaps worth it in this situation, but isn't that basically paying protection money? "Nice domain you've got there. Shame if anything happened to it."

If you are using their services for something important you should pay for it. I use fastmail not gmail for this reason: email is too important for me to risk on an account I don't pay for. I don't pay for youtube, because I don't care if they go out of business. I probably would pay for facebook if possible (but only if they make it FACEbook - not political memes, offensive jokes, and cat pictures) as it is a good way to keep in touch with distant friends.

But they aren't.

Their URLs are simply blocked by Facebook, who happens to be a popular third-party website.

One could argue that is the whole point behind making life for non paying users harder.

Then how come GeoCities, Heroku, Vercel, GH Pages and others survived?

[base]

They workout the issues like everyone else, and at a certain size the issue is minimized as you are either in several whitelists or human moderators recognise your domain.

Most of those services also let clients setup their own domain name, so a ban is a more of a inconvenience to deal, than business critical like in OP case.

[NonNefarious]

I wonder if these assholes (Meta, Google) could be prosecuted under a Net Neutrality law for blocking particular sites.
