Customize Your Profile CSS Option in Profile

In the profile settings there is "Customize Your Profile CSS"

However the options are nothing to do with css they are;

"Insert Your Profile Header Image Full Url Here"

and

"Additional Ads Slot 1 For User *HTML Allowed you can insert your own html ads code here and it will showed in profile page"

"Additional Ads Slot 2 For User *HTML Allowed you can insert your own html ads code here and it will showed in profile page"

I do not want to allow members to post ads and possibly inject malicious coding. Is there a way to remove those "ad slots"?

I dont understand why this setting is called "Customize Your Profile CSS" but I hope there is a way to remove it as I do like the themes features
