The Europe one still isn't working but here are links to two more anti-ACTA petitions.
Link 1Link 2@Hikari: You should still be fine coming on here for another year. After March of next year though who knows.
KofK could be shut down for any number of reasons. Our discussions on anime/games, being a pet site and having a much larger site (like neopets) shut us down, or for their avatar system (a place like Gaia Online could maybe muscle KofK off the internet).
Big sites like these could try to 'copyright' the 'idea' of online pets/dress-able avatars. Even if they were ultimately denied that claim by law, KofK would be down during the legal proceedings and might not be able to come back up. As far as the big players are concerned, that's a victory too.
