Do internet tracking services honor Do-Not-Track seriously?

And why is Basilisk's DNT default setting disabled?

The trackers you'd really like to honour DNT ignore it.

If it's off by default in Basilisk, it's probably cos it can break stuff.

A user agent MUST have a default tracking preference of unset (not enabled) unless a specific tracking preference is implied by the user's decision to use that agent.

I guess you have been answered already but it is disabled by default unless you turn it on for a specific purpose.
