Why is the Thunk Provoking sticker blurry?

[Penis Drager 2.0]

Most of the other stickers are decently hi-rez but Thunk is pixelated and blurry and it bothers me.
Lunacy too but it's less of a problem.

Because you're gay

 

[We Are The Witches]

Probably because they're loaded as a png instead of an svg.

It made you think, didn't it?

I dunno, it looks fine to me.
