I was saying the tag existed to describe the ship and laofuzi decided to use it for something other than the ship.
 
That said, I did research into the nine shipping images:  
raricora is also used, but both tags being used to refer to the same ship started about four years ago, and about two years ago, there were efforts to fix this by making raricora the only Rarity/Zecora ship tag, at least on the earliest images by John Joseco, but six months ago zecority was put back on them. Both the effort and reversal were done by background ponies, so no big deal there.  
The next image after them had a staff member add the zecority tag during that time four years ago, making any effort to fix it now not as simple as a unilateral tag removal spree on the other nine.

…is it really a ship when it’s merely the alternate hairstyle? No one’s tagged “flutterdash” on Rainbow emulating Fluttershy’s hair and personality from “Newbie Dash”; that seems like a similar situation here.

Zecority is apparently the ship name.

Reminds me of my favorite boxer

Punkora

I really like her mane

@FSin  
I almost think a fusion would work; dyed like the left, top styled like the right.

@FSin  
Same here.

Ooh, I like the left.
