Avatar Picture Changing to a SMU-F. Is this a Malicious Script or an Easter Egg?

[Mage of the Wyrmkin]

I have noticed that since I responded to a discussion thread in one of my PbP games that my avatar picture will turn into a blue lovable character whenever I type this word in the body of the message(SMU-F). I am wondering if this was done intentionally by Paizo or if it could be a malicious script?

R is the fourth letter of the word that I left out in the word above.

It's intentional and very smurfy.

And it's Murphy, too

It is the remnant of an April Fool's joke from the early days of the forums.

Its smurftastic is what it is.

[Totally Not Gorbacz]

Smurfs don't exist.

[the Smurfoz]

No smurfs here

Smurfin smurf.
