2 By altering the whole database you altered the site's history, changed its face. A web page should be available as it was created at the time, either rightly or wrongly, and not only in Wayback Machine. A site's past doesn't belong exclusively to its legal owner; we have enough Stalinist crap from the likes of Google.
I actually kinda agree with this, at least for the content (design can and should change).
Keeping the score for the old reviews and simply not using them going forward would have been better IMO.
Stalinist?
This is pure capitalism, bud. And guess who the sole owner of the site and all materials stored from the past? W1zzard, who you just demanded to do something.
Technically this is obviously correct, but the nature of the internet should make it a perfect cache of history (I really don't know how to put it). Put something on the web and it's there for all to see, deed's done, no takebacks and so on. In a way this is a revisionists move, like the people who say/do something dumb and then try to erase all traces of it, but way less serious of course. Editing the past just feels fundamentally wrong.
I really don't see how it would have made things worse by making an announcement and include a link to that announcement in the Conclusion page in future reviews.
In the end I don't care though; the scores were crazy arbitrary and getting rid of them was a good idea I think.
