We have an e-commerce site that allows you to check out as a guest.
An individual has been using it to check if stolen credit card numbers function.
We plan to add invisible captcha, which helps for people using scripts/headless browsing/automation, but it doesn't stop someone from manually using it this way.
We could track a cookie that starts to prevent/timeout the user from checking out if there are enough recent requests, but that's easily workaround-able.
It seems like a situation where it can't be limited too much further because normal users need to be able to check out, but are there any other specific methods that would help?

Maybe you can setup a web scrapper that fetches the page on a periodical basis with the help of a background job, you may begin with PHP and Cron.

I made a simple website using html and php.
How to save to a separate file:
IP address of user that came to the website
Time each user spent on the website
Thanks
I think it's a good idea to use Cookies in PHP that unique user just has a unique cookie, not Ip.

Recently I decided to learn Javascript and have been trying to create a script that will put a border around empty elements before the form is submitted. Essentially I want the form to be live validation and notify the user before they click submit. Any help would be greatly appreciated.
There are very many plugins if you want to use jQuery as your title suggests:

Just pick whatever you want :-)
Or if you want to use plain JS, just search "javascript form validation" on google, you'll find thousands of entries, e.g.
http://www.learn-javascript-tutorial.com/javascript-form-validation.cfm and http://www.tizag.com/javascriptT/javascriptform.php

I am making an open-source addon for firefox and chrome called and I am wondering if there is a way to control an email service like yahoo using javascript?
You can control the look of the page and probably (although I cannot be sure) send and edit messages without having to use the on-page buttons, but you cannot do server-side stuff such as logging into an account from a page without a log-in on it or sending a message from a page other than the email sending page. If you have any specific questions about controlling one specific thing, please add them in the comments, and I may answer them.

As an example, let's assume I want to prevent users from using auto-clickers. Is it possible, and are there accepted best practices when doing this?
Nope, it is not possible. Someone can always turn off JavaScript, modify it, run their own JS-code, etc, etc. JavaScript should never ever be used for security reasons.
However, for AJAX-requests you could implement a minimum interval server-side (like on Stack Overflow).
