Writing a rule parser I noticed the following rules in the main easylist set:
||adm.fwmrm.net/p/msnbc_live/$object-subrequest,third-party,domain=~msnbc.msn.com,~www.nbcnews.com
||graphics.pop6.com/javascript/$script,third-party,domain=~adultfriendfinder.com,~adultfriendfinder.co.uk
Looks to me the domains should be separated with a pipe, not a comma.
