"No relists. Relisting is creating multiple trades for the same purpose or listing the same item in multiple trades excessively. You cannot have multiple trades open with the same goal, and you cannot have an excessive number of trades open for the same item."

Your trade was closed because it was identical to the one you had open here:
http://www.tf2outpost.com/trade/12173013

Probably because your profile settings dont meet the requirements of the site.
Check that your settings here:

Meets up with the requirements here:

This happens when you do that, if you want it fixed you will need to verify the intergrity of your tf2 game cache.

Does updating tf2 work as well? (When a new update comes out)

No, only verifying or editing the document you changed will fix it.

From the link that was posted by HappyStix:

"First of all, a clarification must be made: the staff does not have any direct control over the advertisements that are displayed on the site. We also do not see any advertisements ourselves due to the administrative ranks we have. All the advertisements are managed by a separate and dedicated Ad Team, to which we send a report every time a bad advertisement is caught - to have it removed from rotation."

If you want these ads taken out of rotation you need to help them out by giving them the information they request from users experiencing these redirects.

This happens when you do that, if you want it fixed you will need to verify the intergrity of your tf2 game cache.

Did you do the equip region glitch?

Please use the site for trading, not the forums.

I didn't blame the staff, and still don't. One of the ads is malicious, and I'm attempting to find another person having a similar experience

You aren't the only one having these redirects, and he wasn't claiming that you are blaming the staff. The post linked shows you how to help the staff out by reporting these ads.

Usually you just click the two arrow button next to their name:

Otherwise you can go to their profile and click offer a trade on the dropdown box on their profile:
