So, it looks like that I missed just one April 1st joke by theymos - in 2015 because back then I didn't had Bitcointalk account. If I remember correctly, I have screenshots of all other pranks. But I can't upload it now because it's on different devices.
And I was actually fooled for a second by additional rank requirements. It looked a bit strange and suspicious, but I forgot to look at calendar.
And I can't forget last year when people were actually posting their selfies with a passport .
