Someone enabled them through the GUI and the status is possibly being  
retained (see the documentation about Retention) _or_ you have  
multiple nagios daemons running, one with an old config with it  
enabled and one with a new config with it disabled.

Only if you have a working host check_command. Active/passive services  
or number of services down makes no difference at all. When any  
service on a host fails, the host's check_command is run. If that  
returns a non-OK result, notifications for services on the host are  
suppressed until the host recovers and a single host notification is  
sent (if specified). If it returns an OK result (or isn't specified),  
notifications are not suppressed for services on that host.
