Banning a company name is usually a standard measure when someone spams, so that spammers don't try to register multiple nicks and spam the same company name.
We usually lift the censors after a certain period of time, but we can forget quite easily (considering our 'filters' list scrolls on and on and on and on....).
If you'd like to post about a banned company but it's still censored, drop us a line and we'll usually lift it. For the really serious offenders, the mods usually confer before deciding on the appropriate action.
Hope this clears up the issue a bit.

(or is that 2.2 cents inc. GST...?)
