Many online games allow players to contact each other via player-to-player messaging, chat rooms, or public discussion areas. What qualifies as spam varies from game to game, but usually this term applies to all forms of message flooding, violating the terms of service contract for the website.

Once a minute doesn't count as spam, else everyone would be jailed for having a conversation in-game. I think 2-3 times a minute is acceptable for advertising an event since it lasts like 10 minutes at the most (usually much less), and only happens a few times a day.
