How should Sunny Way's speedpaint thumbnails be tagged?

Background Pony #FA6F
Some of them are tagged based on what’s visible in the thumbnail, while others are tagged based on what’s in the original image on Furaffinity. Which one is right? I’d remove tags that don’t apply to the thumbnail, but I don’t want to run afoul of the “the artist’s intent takes precedence” rule.
 
For example, https://derpibooru.org/images/2436209 is tagged watermelon, but none are visible in the thumbnail.

I’d say to tag only based on what’s visible. Whenever porn gets cropped for the sake of advertisement or making SFW, the explicit stuff isn’t tagged. This is more or less the same thing. Plus, Sunny Way is generally not too great at tagging.

Also, there should be something to separate pics like that since they’re not actual art, they’re like OP said thumbnails, or like I call them: ads for speedpaints.
 
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.
