I've spent way too long trying to find an answer and I still couldn't find anything. If I block someone on Threads, can they still see/reply to my comments?

On shitholes like Reddit I can block someone and they can never reply to any of my comments, but what about on Threads? Someone's being a fuckface, and I wanna tell them to stop being a fuckface (in acceptable social media language) and then block them, because fuckfaces can fuck off.

But I don't want them to ever be able to reply to me, or interact with me ever again, including my previous comments they already replied to.
