Description

Discord introduced auto moderation and the addition of it in the docs can be found here https://discord.com/developers/docs/change-log#auto-moderation.

Example

To create an auto mod rule you would do

AutoModerationRule rule  = AutoModerationRule.MessageSend.preset("name", TriggerType.KEYWORD).setKeywordPresets(KeywordPresetType.SLURS, KeywordPresetType.PROFANITY).build();


or

AutoModerationRule rule  = AutoModerationRule.MessageSend.keyword("name", TriggerType.KEYWORD).setKeyword("butts", "*cats").build();

and then 

guild.createAutoModerationRule(ruke).queue();

I neglected going through and fixing every syntax inconsistency, but I hope the point is made. Also needs more docs. Looks good otherwise!

[RealYusufIsmail]

Got the point, and will clean it up tomorrow or today

Dead PR ?

@MinnDevelopment Planning on working on this pr now. Is there any point or shall I wait

[MinnDevelopment]

I won't have time to look into automod any time soon. But we might be interested in making a new PR from scratch in the future. Can't make any promises right now.

Thank you for your effort, but we've decided on a different design. This PR will be superseded by #2429.
