Since you left the chat, I tried to submit a SADX stat. I had this one once:
Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /submit/stats/confirm.

Reason: Error reading from remote server

Apache Server at www.soniccenter.org Port 80

Then I got something that had no error code that said:
Access Denied! Your address is blacklisted. More information about this error may be available in the server error log.

It seems that your IP address is on the Spamhaus blacklist. It's a dynamic IP (AT&T wireless), so it's likely that someone who had your IP address previously was doing malicious stuff.

I added the IP range to the whitelist, so you should be able to submit stats now.
