Can one add friends too fast?

This isn't the first time I've received this message from Digg. I dropped the error message in to Google and can't seem to find where anyone else is complaining about this.

Uh... why the hell not? Digg, wonderful tool that it is, often is responsible for bringing sites to their knees with an influx of traffic. Surely they've developed an infrastructure that is robust enough to handle me trying to add a couple off friends every five minutes.

Or maybe this is how they keep the site up? Hrm. Wonder how many others are turned away by this message? Would the Digg community be larger if this didn't happen?
