My idea is to allow users to learn from their mistakes with educational resources
When a user makes an unacceptable comment that is removed by a mod or admin for violating the Reddit TOS, if it wasn't seemingly deliberate - allow the user a chance to educate themself on why the content was wrong.
For example, if a user makes a comment that breaks Rule 1 of the TOS, have a DIY course that educates the user on what identity-based hate or attacks looks like, why it's a problem, etc.
Currently the comment just gets deleted and the user cannot even know what the problematic comment was - so it's impossible to know what went wrong.
If the user opts to complete the mini-course, give the user a second chance. Sometimes it's not malicious, it's simply not knowing the boundaries of what is acceptable to say on Reddit, or not realizing that what has been said is hateful, stupidity, etc.
I think providing resources not only helps Reddit be clear on the rules, but is a service to society by educating people on how to simply be better.
