I don't see a universal way of doing this, but I'd try a match against a
References header.
For instance, your e-mail has this References header:
References: <e1hihdn-00068j...@enotuniq.net>
<20190703153922.gz2...@eeg.ccf.org>
<e1hihr4-0006a9...@enotuniq.net>
So, assuming that you wish to block threads that are started by me,
participated by me, etc, you'll need (:h should correctly process a
multiline header):
if ( /^From:.*recovery...@enotuniq.net/:h )
to /dev/null
if ( /^References:.*enotuniq.net/:h )
to /dev/null
But that assumes that everybody in the thread are using a sane e-mail
client. And relies on Message-ID that can include literally anything
(but it does include a domain most of the time).

That's an option too. The obvious disadvantage is that you see e-mails
and (sub)threads that you want to delete.
