If you use Google Chrome, I just found Unspoiler
~Link~ , which is an extension which will (largely) block spoilers for you (all you need to do is add in keywords, like destroyer, The Red Queen, TRQ, Obernewtyn, etc, etc). It might not completely hide it (looks like it doesn't hide posts here), but it will certainly warn you if there is a mention (at the top of the page).
I'm sure there will be other, similar things out there, but might be a good idea to use something like it - try as anyone might (i.e. I'm sure we'll request it be kept to one thread, and not posted on FB), there's always going to be something that might slip through
