I mentioned this on a late(r) night thread a couple of days ago.
Donaldinho - have you ever wondered where your replies have been going to?
I think I have found the AB 'Black Hole' - look at date of original post and follow it through.
Ha- that is weird. Maybe Donalidhino has that original thread saved as a bookmark and has it open alongside current threads then when he wants to reply he clicks on the tab for that 2013 thread
Captain- maybe it's the confusion caused by having a crossword thread with the title Crossword. I wonder if people who are trying to reply to other posts entitled Crossword are accidentally clicking on this one from the Related Posts lists. There may be others entitled 'crossword' that also attract these random looking replies
