open_proxy_check problem on awardspace

I have a wordpress website hosted by https://www.awardspace.com. They use a badwordlist that filters some keywords like eBay, Paypal, etc. Then I had a problem with the “option-discussion.php” on my wordpress dashboard. Looking into that page’s code I found the term “open_proxy_check” and now I know that this page was not displayed due to the “proxy” word, that is filtered by AwardSpace bots.

I want to know what this “open_proxy_check” is for and which functions does it have on my site.

can I modify the code of “options-discussion.php” page without interfere on my blog? how to?

sorry for my english. thanks.
