  anything to do with kumquats
  

Because the bad word detector is erroneously detecting bad words in those names.

Kumquats are a type of orange native to Asia that gained sudden fame on the scratch forums when a member of the scratch team found out that their signature had an image in it hosted on a website that was no longer supported. Instead of trying to remake their signature, they instead put something to the effect of “an evil kumquat ate my signature” there instead. My guess is that a lot of accounts where being made with something in their names like “evilkumquat” that the ST decided to ban it.

As for the other, I don't know.

I could see why “kumquat” would not be allowed — a subset of those letters is a misspelling of an inappropriate word.

I could sort of see something similar with the first username, but this is less direct. It's probably best not to get into details, though, just to avoid talking about inappropriate words.
