Well, animation is definitely an "Art", which is just a hair more specific than "Creative"; there are many other kinds of arts from Drawing, Painting, and Pottery, to Dance, Theatre, and Mimery. There are MANY kinds of art. And none of those different arts have their own separate overall "Category", and it seems it would not make any sense logically for Animation alone to be split off from Art, either.
Animation is in fact... well known as a Visual Art.
Streams can be tagged "Animation" as one of the tags in the dashboard --- Animation is a proper tag that things can be searched by; just like any of the other kinds of Art.
I would suggest an alternate way of allocating emotes to affiliates.... Give affiliates some milestones they can graduate to similar to how partners unlock emotes by number of subs - Let an affiliate have up to 4 Tier1 emotes instead of just one. If emote slots on the site are a limited resource, then give more of them to Affiliates with community to justify it and allocate fewer emotes to new startup affiliates --- this would also discourage people making affiliate accounts just to make a set of 3 personal "vanity" emotes: its more beneficial that those slots go to the affiliates who have some viewers and subscribers.
For example, possibility would be:
To unlock first Tier1 emote - Reach 15 sub points.
Clawback: Affiliates with currently no subs other than themself who never reached 15 lose existing emotes.
To unlock a second Tier1 emote - Reach Level2 affiliate status.
To unlock a third Tier1 emote - Reach Level3 affiliate status.
To unlock fourth and final Tier1 emote - Reach Level4 affiliate status.
To unlock one Tier2 emote - Be a Level2 affiliate, Reach 30 total sub points and at least 5 Tier2 subscribers
Clawback: Affiliates with currently no tier2 subs lose their existing emote slot.
To unlock first Tier3 emote - Reach Level3 affiliate status and at least 1 Tier3 sub.
Clawback: Affiliates with currently no Tier3 subs lose their existing emote slot.
Tier1 Affiliate - Base level
Viewers can only gift or subscribe at Tier1 until after "level2 affiliate" is earned
Tier2 Affiliate- Maintain 30 or more unique subscribers for 60 consecutive days and 20/more avg. concurrent viewers over 60 days.
Viewers can only subscribe/gift at Tier1 or Tier2 until after "level3 affiliate" is earned
Tier3 Affiliate- 90 Subs for 60 days and 40/more avg concurrent viewers over 60 days.
Tier4 Affiliate- 200 or more subs for 60 days and 60/more avg concurrent viewers over 60 days.
The actions such as blocking a user completely from even Read-Only access to stream and chat are extremely severe and unreasonable for mere chat rule-breaking --- Twitch broadcasts are supposed to be public content. I believe these options should only be available to Twitch site admin staff, and only in response to a serious Twitch ToS violation such as harassment has been reported that would warrant suspending the user from all access.
