4) Ban people who can't spell buses.

bus
n. pl. bus·es or bus·ses
[snip]

It's not the OED I know, but is accepted.

Accepted in the US, maybe. The site uses American dictionaries and is
based in Los Angeles, so it's not surprising that it includes the
American variant spelling "busses". The plural of "bus" in British
English is always "buses". (Source: New Oxford Dictionary of English,
2001)

Given that the derivation of "bus" is as an abbreviation of "omnibus", I
should b* well hope so.
