cohost.org##div.renderIfVisible:has(div[data-view='post-preview']:has(div:has-text(/^This post has tags you muffled/i)))
as-is, no warranty, etc. if you want to only hide certain tags you have muffled, you could do something like (scroll to the end to see what I'm referring to):
cohost.org##div.renderIfVisible:has(div[data-view='post-preview']:has(div:has-text(/^This post has tags you muffled/i):has(span:has-text(/\b(BAD TAG|ANOTHER TAG|THIRD TAG|AND SO ON)\b/i))))
(the tags don't need to be in all caps)
