Huge Bandwidth usage on an empty forum
 

Does anyone have any suggestions on how to limit the huge bandwidth usage on a vbulletin forum, that has only three members and maybe 20 threads total? I'm talking 400 - 650 MB of monthly data outflow.

Here is some more strangeness... The IPs won't resolve...

Listing domains, sorted by the amount of traffic.

Mayby some one hotlinks your images?

Forums are massive bandwidth hogs. You may have 20 members, but when a search engine crawls your forum its like 100 people clicking every link on your forum for 15 minutes. And that happens every day from many different spiders.

the only way to really help bandwidth is with special htaccess file that can govern it
google or yahoo bandwidth usage and htaccess ..something like that
