All most wise and perfectly logical.

I suppose it's an extension of your I don't post fic to my personal LJ anymore because too many people who read me aren't fannish/aren't into my fandoms self-censorship, though: the same principle, but applied to an archive which is presumed to be 'not into my fandoms' (or pairings, or whatever), even if only by weight of numbers rather than any intended bias. Which of course is why people like you going 'hi, actually here is some Four/Adric' is a good good thing.
