# GroupMessage sends a private message to a group.
|
|
# It will also avoid sending the same message repeatedly, which can happen with
|
|
# notifications to moderators when spam is detected.
|
|
#
|
|
# Options:
|
|
#
|
|
# user: (User) If the message is about a user, pass the user object.
|
|
# limit_once_per: (seconds) Limit sending the given type of message once every X seconds.
|
|
# The default is 24 hours. Set to false to always send the message.
