How does creating giveaways from games that we in bundles work now?

I was about to redirect you to the FAQ using some kind of douchy comment, but it seems FAQ is utterly useless as for now... so here you go.

Basically: the first bundle games worth $25 fully count towards your score; any bundle game past this mark will contribute only 20% of its value. Bundle games are marked by a star (*) behind their name while creating the giveaway.

Also, the max contributor value you can reach with bundle games is $30

I have another question, the tos of humble bundle says that you cannot give to anyone your download link page but there is nothing(or at least i did not found it) about the steam keys, in the general help however it says to not give away the keys of the games you already own. My question is, if you already have the game in your steam library and you cannot give your key, the key is useless must remain unused in the humble bundle page? Also if the tos does not talk about the keys but this is said only in the general section of support, is this valid?
