Let bots use notes on users like normal users do

[ImNimboss]

Bots could use the "Note" feature that normal users see on the profiles of other accounts for a mini-database of sorts, it just seems like a handy inbuilt way to store information about users

Discord isn't meant to be used as a database for bots, you can store whatever info you need on your own server

I've never used notes on a serious level, but if I ever were to, I still would not see the benefit of it over your own database. Client enhancements such as these shouldn't be relied on for your bot's needs.
