Default The Forum javascript that cause 200% CPU load

This is more for the technical operators of the Corvette Forum.

There's a big problem with Safari and other webkit browsers on Corvette Forum, which cause many computers to run excessive CPU and memory loads.

I've traced a ton of this to javascript from your various ad systems. There are several different bugs in different ad code, which pretty much get stuck in loops trying to load resources from ad and tracking servers on the net, which don't load for various reasons, and they tight-loop in JS trying to reload them. That causes enormous CPU load and gets the fans cranked up on my laptop.

This bug in particular, is so frequent that I'd like to bring it to your attention. Perhaps you can work with your advertising partners to fix it, as it isn't a difficult bug. But as you can see in this log, it causes enormous JS loading.

When this occurs, are you seeing an ad block that may appear as black in the footer or header?

I think this is related to a known issue we've been working on. When this happens, atleast on Google Chrome, an endless loop of retrievals causes some pop-out menus to not work correctly.

Possibly, hard to say since I'm not sure where to look. But right now, 160% CPU load, with this at the bottom of the page:

Hmm, seems like the black block in the AD corresponds with the CPU load. Had a good run of normal browsing when that block was showing a normal ad. But now it went black and

There's tons of other crap JS code, including attempts to access localhost from javascript. Not sure what that's about, other than a bonehead coding mistake or someone probing users for sandbox holes.
