@JenK This should probably be blacklisted. Same level too.
P.S. I just found out that the same algorithm to allow typos is used on the WK search function. I looked up “attendance” and “absence” came up as well. So…that’s why I always get a bunch of words/kanji that are not what I’m looking for in the search bar 
Edit: it may just be that “attendance” is part of “nonattendance”. 
Further testing is needed
I accidentally typed “horse” and it got accepted…
A horse is a horse of Coarse of Coarse…
This wasn’t accepted, but I was just reviewing 后 and I knew it meant “empress,” but sometimes I get excited and start typing without considering if it’s asking for the meaning or reading, and so I typed out “kou” (it was asking for the meaning), and my brain recognized that something was off, so it filled in the blank with, "Oh, she must be wanting to type “KOUICHI.”
I mean, close enough, right? I feel like Koichi should be an accepted answer there.
Empress Koichi 
It’s on the (hidden) whitelist
Wow, I did not know that even existed 
Answers can be blacklisted too
Preservation and conservation are synonyms, IIRC, so them both being accepted would make sense.
Possibly the hidden whitelist as mentioned earlier?
Nope, plain old typo allowance
I just added this to the blacklist.
I’ve been awake 5 minutes. The sun hasn’t risen yet irl. I knew what I wanted to type. My fingers rebelled.
