I did not test on a forum with as many cats as yours with googleads, groupon ads, livesupport, some sort of profilehover js and whatever else you've got going on there, which appears to be quite a bit.
Indeed, this may not be for everyone.
You can surely wrap this with
if tags of some sort and only show it on certain forums. Or, set it as I have on my test forum to only show for guests.
GL!
