If it was legit a prank it probably involves some joke or conversation that happened within the team environment. One of those "you had to be there" kind of things, bit like that whole rubbish issue made over James Graham by that channel nein reporter. Hence it looks weird/dumb for all of us looking on from a distance.
Every decent work environment I've been in has had pranks and jokes, would be a fitting end to the 2021 season that NRlol finds a way to sanction a prank. Talk about the fun police.
As for all the people who immediately interpreted this as greed and avarice... fair dinkum...
