Either that or you are all just really good at doing ptich fork weilding mobs, an Internet tradition since 1999.
If you want to boycott it, then boycott it which means stop using it, not defacing it. What you are doing is a DDOS.
Its their website since Cmdr Taco sold out. If they wanna trash it then, tell them you don't like it, stop using it and let them wipe out their investment if they are that stupid. It would probably be better if someone with a heart and a sole started a new version anyway. Slashdot has been pretty much soulless since Taco sold out to VA Linux anyway.
If the people that run the site have are as malevolent and clueless as you say, this little mob isn't going to save it in the long run anyway.
