I tried this as it removes the quote block completely
if (ignoreList.includes(authorMatch[1]) && quoteBody) {
quoteHeader.parentElement.remove();
I suppose the outcome would be the same, I happened to make an observation.
Because if you remove the quote, you will probably think the guy replying to the ignored user is talking to someone else (like the OP). You still need the quote indicator to know he is replying to that guy.
