a question of spoiler etiquette on social bookmarking sites

I try to tag every fanfic I read on del.icio.us so that I can find it again. Now I'm reading some post-DH stuff and naturally my regular tagging (which includes names for all characters in a story for example) as well as the summary blurbs (which I've tried to be better about including in my links), would contain spoilers for DH. I know some people subscribe to del.icio.us feeds or just browse there, and it's not like I can spoiler cut. I'd really like to keep with my bookmarking and tagging routine, but I wonder whether I'm going to get lynched for having tags with spoilery character names. I could make all my post-DH bookmarks private, and unlock them later, but that negates the point of using a social bookmarking site, and I may forget about the unlocking, because I tag a lot of stuff, and even if I have a post-DH tag to find them all again, there's afaik no mass action for making bookmarks not private, so this course of action is somewhat inconvenient. So how should I handle spoilers on a social bookmarking site? What are you doing about your spoilery bookmarks?
