The current moderation is unfair and one-sided...

It's clearly stated on page 8 of the rules that there are three types of feats, Skill Feats, Power Feats and Card Feats. The definition of each of these terms is also stated on that page:
THERE ARE THREE TYPES OF FEATS.
Skill Feats: When you gain a skill feat, check one new box in the
Skills section of your character card. Skill feats add a bonus to a skill
of your choice: you’ll add the number next to the box you selected to
any check attempted with that skill. So if your Charisma die is d10,
and you’ve checked the “+2” box for your Charisma skill, you’ll roll
1d10 and add 2 when you attempt a check that uses Charisma. (See
Attempting a Check on page 11.)
Power Feats: When you gain a power feat, check one new box in
the Powers section of your character card. Some power feats give
you new powers, such as increasing your hand size or making you
proficient with weapons or specific types of armors. Other power
feats improve your character’s existing powers. If your character has
a power that allows him to add 1d4 to another character’s combat
check, and you’ve checked the “+1” box next to it you’ll add 1d4+1
to the other character’s check. These bonuses apply only when using
the power on your character card; if you instead play a card with a
similar power, the feat bonus does not apply.
Card Feats: When you gain a card feat, check one new box on the
Cards List on your character card. Each card feats allows you to put
one more card of the type you choose into your character deck.
After you choose a card feat, use the new number on your Cards List
whenever you rebuild your deck.
