Spamming for comedic effect, dumb memes, not having to try too hard, casually chatting in the middle of games, off-color jokes; I always thought these things were what made Sandbox a relaxed fun place to hang out and play games.
Spamming isn't black or white. Sometimes it's innocent, sometimes it's just being disruptive and mean-spirited. The latter doesn't happen so often to warrant a crackdown on spam.
Supporting vios for simple spam just seems like calling in the fun police.
spam is actually pretty good if you put it in ramen or other similar types of noodles
