Seeing as everything that's currently keyworded as speedpaint for Sunny Ways, §@`artist:sunny way,speedpaint@`§ works as a complex filter to get rid of them. But that might not last forever, which could have the price of missing something one wants to see, like has happened with other things.
Seeing as they're not actual art (ad for a speedpaint that's linked elsewhere), there's no "artist intent takes precedence" beyond what's actually visible, IMHO.
