The 4chan word filter was, apparently, put in by the 4chan team just for the heck of it. When submitting a post onto /b/, any specific word or phrase (typically a meme-related one that was over-used) may have been changed to something else. The mods made the word filters out of annoyance with over-used memes, for the “lulz”, or both. Eventually, a few word filters were added to other boards other than /b/, specifically /v/ and /k/, but were later deactivated. Wordfilters have also themselves developed into memes both on /b/ and elsewhere, some posters have taken to referring to furry as drama, loli as duck, etc. Thus, a good (or at least memorable) wordfilter can survive long after being deactivated.
In March of 2007 all word filters would be made inactive, including the “PENIS” filter, which was widely considered to be the most loved of the wordfilters on /b/. Some of the word filters were brought back again later.

Moot (lowercase M)= sigourney
penis (caps) = PENIS
Mods (lowercase M) = the people’s champions
Faggot (lowercase F) = candy-ass
Vagina (caps) = VAGINA
Nigger (lowercase N) = roody-poo

I’d say it’s a meme since it’s spread to other chans as well. For some time after Steve Jobs’ death, “Apple” was wordfiltered to “Dead nigger storage” on 7chan’s /eh/, and “retard” is wordfiltered to “strawberry” on 7chan’s /b/. Wordfiltering also takes place on certain online game servers in games like CS and TF2.
