"""
|
||
|
|
Occurs whenever a message is deleted. Note that this event isn't 100%
|
||
|
|
reliable, since Telegram doesn't always notify the clients that a message
|
||
|
|
was deleted.
|
||
|
|
|
||
|
|
.. important::
|
||
|
|
|
||
|
|
Telegram **does not** send information about *where* a message
|
||
|
|
was deleted if it occurs in private conversations with other users
|
||
|
|
or in small group chats, because message IDs are *unique* and you
|
||
|
|
can identify the chat with the message ID alone if you saved it
|
||
|
|
previously.
|
||
|
|
|
||
|
|
Telethon **does not** save information of where messages occur,
|
||
|
|
so it cannot know in which chat a message was deleted (this will
|
||
|
|
only work in channels, where the channel ID *is* present).
|
||
|
|
|
||
|
|
This means that the ``chats=`` parameter will not work reliably,
|
||
|
|
unless you intend on working with channels and super-groups only.
