Allow bots to send ephemeral messages when deleting a users message

[CottageDwellingCat]

When a lot of bots delete messages they need to inform users why their messages was deleted (so they know their message contained a blocked word, or why it broke the rules). I think it be useful add an object in the delete message endpoint called show_user_auditlog_reason, when the property is true an ephemeral message will be sent in the channel the message was deleted from containing the X-Audit-Log-Reason for the deletion, and the text of the deleted message. This would also force the deletion to show up in the audit log (so server admins could validate reports of bot spam).

Adding on to this, I think it would be cool for bots to be able to send ephemeral messages in any scenario.

giving bots the ability to send ephemeral messages in like every senario could be a big fuck up since many people can abuse them. The ways to abuse the power to send messages which aren't stored in discord database shouldn't be discussed because it would give ideas to people, and someone asked this thing to mason too and he directly rejected it
his words to be exact

We very explicitly do not want ephemeral messages to be sent "un-authorized" right now due to abuse cases. I won't get into too many details about why because I don't want to give people ideas of how to do dumb things, but it's a conscious decision that probably isn't changing anytime soon

This is a nice idea but it could be exploited, that's what is the problem. This is why (and probably for a few other reasons), ephemeral messages are locked to Interactions only.
(I too initially had this idea and thought this will be wonderful, but the exploits this could give rise to, is huge)

ah. that sucks, but I can understand that, thanks

Regular messages can't be moderated either since they can be deleted right after being sent (for example, a bot that DMs you something and then deletes it, or even in a regular channel). You can see the generic TnS support for such things in this image:

There's nothing necessarily preventing them from temporarily storing ephemeral messages for a limited time frame (such as 15 minutes) so attachments and reporting could work with them. They just chose not to. Should be noted that other services, e.g. Slack don't seem to have a problem with it.

The messages would (in this request) have their text stored in the audit log, so if a bot was reported their would be non-deletable proof of the message content.

temporarily storing ephemeral messages for a limited time frame

Then it will not be ephemeral anymore.

ephemeral means temporary, storing it for a "limited time frame" is still ephemeral
