Instead of telling people to post spam in the thread, they should do the same way that is done for example by these:

- https://meet.hn/

- https://book.keybase.io/account#adding-proofs

Those tell you to put a text in your HN profile “about” section.

I don't think the point is to link the HN account to the PF account. I think the point is to spam HN.
