A social network where your anon accounts still get priority in the feed of your followers without disclosing who it is.

Would a Web of Trust be sufficient here?

You endorse a new anon account (run by you) and when people who trust you score the new user's posts in their feed, some of your reputation is transitively applied to the new account, making it more likely for others to see and endorse that account as well.

Web of trust at least leaks plausible correlation, like via what friend this came by.

Do you think the protocol would need to be resilient against collision between all your followers?

Mechanically speaking, if suddenly this new rando account has a high reputation for a certain set of people, it seems like that set would be able to notice that and figure out what they all have in common (following you)

No, I get that Web of Trust is leaky, maybe too leaky for the original idea you proposed (imbuing high reputation on an anon account you also operate).
It would be less leaky to anonymously provide zk vouchers to your contacts ("here's a proof I'm one of your friends, this account is cool").
Collusion breaks it though.

That’s not quite the issue I was describing, and maybe I misunderstood what you meant by saying “web of trust”, which is understandable since it’s both a technical term for a pgp scheme and a generic term that could mean a lot of different things.
