Spam

Spamming refers to using a certain move repetitively. Projectiles are the most used spamming moves. This action is sometimes considered cheap, especially when a player uses the same attacks all the time. Some players will use different attack but will have a tendancy to use spammy attacks more oftent. Juggling an opponent may also involve spamming such as repeating Up Tilts. Grabs have also been known to spam. This is known as a chaingrab. Ideally, the spammable move is fast, has little or no lag, and can be used from a distance. While the game discourages spamming with Stale-Move Negation, the average spammable move doesn't do much damage anyway, so the effect is less noticable. Spamming all the time will make a player's attacks very predictable, so a "normal" player can shield to doge most of the spammer's attacks. Playing with characters with counterattacks or reflectors is also a good way to deal with spamming players.
