Translations:Help:Extension:MassMessage/14/en

If you want to exempt an entire wiki from any and all MassMessage deliveries, you can block the account used to deliver messages (on Wikimedia wikis, this account is "MediaWiki message delivery"). Blocking MassMessage deliveries would likely be considered highly disruptive. Be careful. Deliveries that were aborted due to the block (or any other restriction such as page protection) will be logged at Special:Log/massmessage.
