"Is it possible for a user to write a script to monitor my activity and down vote everything I post automatically?"

As a programmer, yes this is achievable.

"As soon as I press the button to Submit post, there is a downvote."

I doubt that's true, what evidence do you have?

"Does PerlMonks allow members to set up an automatic thing?

It's against the rules, and the spirit of the place, which isn't to say someone can't do it, but there's no evidence of this. Historically our most down-voted users have claimed such things existed, and those with the powers to check such things proved otherwise.

"Secondly, how would I do that without being logged in?"

1. A user has to be logged into vote. 2. computer programming.

"Thirdly, if I wanted to write an automatic down voting script, it would have to download a page from PerlMonks every second to check the new posts by that user."

"eventually downloading the same page a billion times would raise the awareness of the admins (maybe?), and I think that user would be placed in a timeout. So, how can someone pull this off? I don't understand it.

See all of the above, basic computer programming... it's against the rules... we don't really have the kind of user... and nobody really cares about votes, just pertinent responses/critique.
