Strange thing happens to me when I tried to register with "Banned.video"

While I was registering with "Banned.Video" when I tried to put in a user name no matter what I typed in it was saying it was too long but only after I tried to put in ACDJ/07/19/1970 as a username and the weirdest thing was though not highlighted where I'm to type the user name it show the phrase "downwithbigbro". Strange my life is getting more and more strange... Trust God.....
