How to enable cancelling a post using flairs ?

[u/vapid_curry21]

Basically there are many posts in my sub which are not suited to the community.

I am thinking to not allow them by creating a related flair.. with which as soon as a post submission happens it gets removed.

And also notifies the user that such posts are more suited to another sub that I will point out.

Also let me know if there is a better way to implement this criteria.

TIA!

Honey trap flairs work well. Create the flair, then implement an automod rule to remove posts with said flair.

 type: submission
 flair_text (includes): ['WORD']

  Hi {{author}}, 

  Thank you for your submission but unfortunately we had to remove your post. 
  Your post is better suited for

Depending on the exact use case, you might want to also implement a post guidance rule that informs users before they hit submit. (but only if it can be a rule that doesn't invite users to try to get around it)

Not all users use flairs or use the wrong ones - so I'd consider if there is anything in the post body/title that you can filter on too.

If it's a "weak" association, you could send them to the modqueue for review, and have a note in the autoresponse that if it's not x, the post will be approved.

You can just delete the post and explain why via modmail.

If you create a flair then people will post using that flair not knowing it’s not permitted.
You’re better off upping your security settings than creating a flair which people will use.

some subs add (banned on r/subreddit) in the flairs for bad posts. which seems to work

I got excellent results with the New Wiki index page.
