I've noted on various occasions the auto censor adjusting my posts. I guess it's part of the new world order that we can't mention certain things without altering the spelling or something.
I can only assume "ANONYMOUS" will shortly become non politically correct, (NPC), and you will have to think up something else, slightly different, but without confusing Algie or Lookleft.
How about "Anymouse" if it comes to that?
I hope this helps.
