Yes .. I think the current blocking is only hiding the stuff .. relays still carry the reactions of the people I blocked ...
Btw - that is the difference between "notes" and "posts" .. notes mean default position is no one (except me) may react to what I noted ... posts are open submissions for comments .. or likes or whatev.. We should be true to the name :-) ..
Not sure what the influence was but I know in Japan it’s called note(s) and a boost/repost is called renote
