I don't think this has been requested before.

Start with (info "(gnus) Scoring")

First of all, note that Gnus does have kill files but they are slow and
probably not what you're looking for.

You can use scoring to lower any thread's score.

Look at `gnus-summary-increase-score` for the UI around it, which
constructs a call to `gnus-summary-score-entry`.  It only does a single
score right now, so you'd either have to write some ELisp or construct a
keyboard macro (far easier but less maintainable).  I'd recommend the
macro to see if you want to use this at all.  The effort of using the
macro is *probably* the same as the effort of marking each thread and
calling a function.

My concern there is that the message IDs for killed threads will pile up
and the scoring code is not optimized for lookups. You may end up with a
really long time waiting for the summary buffer. To combat that, you can
use individual score files per group and decaying scores.
