Multiple spoilers per page would work though, as long as the id is different for all the spoilers on one page. I would suggest just putting something like your username with a number tacked on the end for your own spoilers and then hope that nobody else is a jerk and uses your name and numbers as well.

If you do do this, keep in mind that some users may have a different posts-per-page amount than you do, so don't recycle ids for spoilers that would be close together in a thread.
