I don’t know of any way of doing it through wefwef, but you can block a community when using the website version of Lemmy, just go to the community, click on “Sidebar”, and click “Block community”
I think it open on the instance that it was posted and if it’s not your home instance, you can’t do much. A maybe more feasible way is saving the post, then going to your instance on your browser or another app that supports blocking and do it there.

If you open a post and click on the icon between the save and the reply icon, it opens that particular post in the webbrowser. Might save some steps.
