Alright I've got a good one for you all.

Say hypothetically you wanted to kill the organic traffic of your site, how would you all go about it?

The clause is that this needs to be a gradual decrease of organic overtime, not a sharp obvious drop to 0. So white text keyword stuffing is out of the question, as Search console would send a report to the admin listing why they penalised, and would see a big drop, the jig would be up.

Would love to hear what the fine people of r/seo would do if they were faced with this challenge.

Hypothetically of course...
