I wonder if this should work in the forum Blocks area?
I have the following:-

if (is_member_of($vbulletin->userinfo, 6)) {
$my_output = '';
} else {
$my_output = ' google adsence code......';
}
return $my_output;

However no matter what usergroup I choose the advertising is always displayed. 6 is Admin usergroup and I am admin. I choose usergroup 1 for not logged in, and try that without being logged in, but it still displays the advertising.
I know its not a cached issue, as I just popped in some test text, and that was displayed.
