Let me say from point 1 this code is not found to be malicious in any respect.
It can be found in front end SPOF reports so it could make websites load slower.
It is flagged here as tracking code: http://hosts-file.net/?s=ads.srax.com
It is on stealth IP independant nameservers: http://who.is/nameserver/dns1.stabletransit.com/
and websites are served from Rackspace Cloud - -d3c3cq33003psk.cloudfront.net
