Spam typically refers to unsolicited junk mail and blog comments. Spam can consist of legitimate advertisements for products and services, or may be part of an online scamming operation. Spamming refers to the bulk dissemination of spam posts, or the repetitive posting of spam on public forums.

Spamming is basically throwing out the same move over and over again, 'spammable' moves are usually safe and are very difficult to counter (e.g projectiles).
