Adblock Plus

I notice a new column ! has been added. What is this for?

I notice this column is associated with only the following three filters:

*$domain=hindilinks4u.net
*$domain=whispersinthecorridors.com
/advt/*$domain=hinduonnet.com

Why?

Those filters can't be optimized by Adblock Plus and therefore are much slower compared to the others. For a filter to be optimized, it has to contain 8 unbroken chars(= not separated with an *):

Fast:

/adfilter.js
/ads/advt/*
.example.com/*/advt/

Slow:

/advt/*
/ads/*/advt/*
.exampl*e.com/
