Most forums have an automatic 'censorship' feature (we have one on here too).
That way, certain words when they are typed are automatically replaced with either another word, a row of asterisks **** or, they are just deleted all together.
Mainly this is used to prevent bad language, but sometimes this feature is also used to automatically take out the names of people or companies that the forum owner, for whatever reason, doesn't want mentioned on open forum or via a PM.
