Or is that puzzle shockwave thing ok for Tor users? Maybe they can use it without fear of being discovered? I don't understand for certain what it is or what risks it presents. But still. A simpler captcha might be nice, right?

When you create a new account, why does there need to be a shockwave object on there? This can cause real problems for Tor users. Isn't there a better captcha system that can be used that doesn't lead to the possibility of an IP being revealed? I thought flash and stuff like that was rubbish...
