That this happened around April Fools’ makes me think that someone forgot to instruct it not to partake in any activities associated with that date. The fact it chose The Simpsons’ address in its (feigned?) confusion is a dead giveaway (to me) that it was trying to be funny.
Or rather, imitating people being funny without any understanding of how to do that properly.
Its explanation afterwards reads like a poor imitation of someone pretending to not know that there was a joke going on.
