Well, “cutie mark” and “unicorn” really aren’t needed; the former fits nearly all the pony images on the site, and there’s never been a demand for the capability to search by “unicorn”, “pegasus”, and/or “earth pony”. sitting is probably not needed for most images where it’s appropriate, but in this case, where it’s just a single pony in a sitting pose, I could see how it’s useful.

I suspect someone is reversing some of my tags - I did add those tags within five minutes of making that comment but looking now two of them have gone missing, this has also happened to at least one other picture I added tags to.
 
For example: derpibooru.org/102947 (safe for work)  
I added the tag ‘Pink text’ because there is pink text in the picture along with some other relevant tags.
 
Ether the mods disagree with my tags or there is some tag vandalism going on.

@ARandomVisitor  
You can add missing tags.

Cute picture, as for why I lacks the ‘sitting’ tag ?  
I have no idea.  
Ditto on lack of ‘cutie mark’ & ‘unicorn’ tag.

Cute! c:
