Put Shortly,
They are a bunch pyros in charge of the fire department …
I have not renewed any but I did add some right after the site match was introduced … I gave up with there BS of not being able to answer webmasters questions on another board. One of my clients submitted about 30 urls that are lost in the system so best bet is to not submit any more to INK/Overture/Yahoo if they are domains of gambling or pharmaceutical nature.
