I certainly do like being able to quickly categorize people into groups of those who can find humor in such stickers, and those who will get angry over them. Seems pretty useful in determining whether or not I would want to continue engaging with them :)

Unfortunately it's hard to tell at a glance whether it's a joke or the owner is extremely incompetent (though a quick conversation should reveal that)

Like the 5 people that downvoted my question.
