Because they only track things that have value :p

Last I checked there was nearly ZERO trading volume on yobit -- not sure of the other exchanges.

An illiquid coin gets kicked off of most exchanges

I have asked YOBIT to open up a trading pair between KARMA:2GIVE, but have not heard back from them yet.

That would at least provide some liquidity.
