The difficulty for anyone trying to do that is that they would be attempting
to read millions of pages as a logged in user without a bot flag. So they'd
probably get blocked as a denial of service attack. Even if someone
subdivided their calls and created multiple accounts to read parts of the
project from hundreds of different PCs they would only learn that someone
had filtered in or out certain images.  To replicate the filter they would
need to have each of those accounts flag certain images as filtered or un
filtered - and at that point I would suggest that this has become a much
more difficult thing to hack than simply extracting some of our existing

As your the second person to raise this I'll add an explanation to the
proposal as to how this can be countered.
