Currently, if a user is reverted by Automoderator and receives a talk page message, they receive an entirely new heading and full message every time. This can make user talk page messages very messy for persistent vandals who don't get blocked for a little while. See, for example, User talk:~2024-3342.
Instead, we could be appending a shorter message to a relevant previous heading, which simply notes that another edit has been reverted. This message should also be a system message for translation and local overwriting.
If Automoderator finds a talk page message sent this month, instead of sending an entirely new message, it should instead add an intended response to the last message (in the same section), like:
:I also reverted one of your recent edits to PAGE because it seemed unconstructive. ~~~~
