Re: 1, if you have concerns there's also always the option of not allowing anonymous comments, turning on comment moderation, or even locking the posts to logged-in users which can reduce the likelihood of click-by trolling a great deal.

And yes, it sounds like you are! A great deal of my meta was written in real time in response to a series as it took place. So the posts are very much a time capsule. I've noted the original posting dates in all of those in the author's notes up front. I did once have someone who didn't notice that about them but I think generally people have.
