Already supported; for example: http://lesswrong.com/user/gwern/liked/ and http://lesswrong.com/user/gwern/disliked/ (there's even RSS feeds for those pages! like http://lesswrong.com/user/gwern/liked/.rss Nothing stops one from grabbing RSS feeds and doing any processing they please on them.)

My stupid fanfic chapter was banned without explanation so I reposted it; somehow it was at +7 when it was deleted and I think silently deleting upvoted posts is a disservice to LessWrong.

But really, I wouldn't think a lighthearted parody of a lighthearted parody would cause such offense.
