I know that pretty much all of the allowed 3-letter usernames are taken, but what about 4-letter ones? Does anyone know how many there are?

Yeah, 3 character users were all taken at some point due to a fake class (the rest are filtered). Not sure how many there are exactly, but 4 chars are still available.

yes, four character user names are still available. i even got one ( https://scratch.mit.edu/users/r_tt/ )

I found that @hkcq wasn't taken after ≈ five seconds, so I'm sure that they are not uncommon.

Anyways, the people above have said, yeah there's probably some of them left
Copping some of em out ain't really on my priority list though
