Anti-spam filters

Just signed up for the new (to me...) forums, and had to try five times before I could get past the spam filter.

First question: What shape is a ball?
I typed "spherical", I'm guessing I should have typed "round".

Second question: If we have an Alien Bobble Head what is bobbleing?
"an Alien Head", "alien head" and "alien bobble head" were not accepted. Is the answer "an Alien Bobble Head"?

And then finally, an unambiguous question:
What is the number of the button on the numpad if we start with 7 and move 2 down and 1 over?
"2" was the answer, although I guess I could have typed "two" and gotten more fodder for this post.

I understand the need for spam filters, don't get me wrong, I just found this mildly amusing and felt like sharing.

for the ball one you could have just typed ball.

clearly you're a robot

That woman has a large ass and little material to cover it.

clearly, you fail worse than me on a bad day. D:

Hiroga is awesome.

Yes, I am a robot.

And that inspires awe.
