And here's the official post:
If you haven't figured it out yet, then yes, this was our April Fool's joke.
All user titles have now been reverted to the correct values. And everything I posted about your titles was obviously also a joke
However, in the unfortunate circumstance that you're still finding your account to be stuck with the 'Canon User', 'Nikon User', or 'Doesn't actually own a Pentax' title, then they
actually apply (and you've probably been banned).
Thanks
(to the 10 people who sent in a mod contact form, and the ten others that PMed me) for making this a fun April Fools day, and, while you're at it, I encourage you to go Topeka some other jokes, such as the ones of our great search engine Topeka, as well as Youtube's TEXTp video resolution!
Best,
Adam
