@antimnguyen But what I really want is "Hide boosts from xxx containing the phrase nnn".

Mastodon has filters you can create like this which act globally across all users. It shouldn't be too difficuly, surely, to add a users handle to this to make it even more flexible!

I might very well be interested in tech info from, I dunno, Bill Gates. Not so much my nan.

Right now it is all or nothing.
