This is what not to do

It presents a realistic and detailed walkthrough of six common dark patterns used by SaaS products and subscription services to trap users and artificially extend retention.
Spotted something shady in the wild?
We're building the internet's definitive collection of manipulative design patterns, and we need your help.
If you've encountered a particularly egregious example of dark pattern design whether it's a popup from hell, a cancellation flow that makes you question reality, or a pricing page that would make a magician jealous we want to hear about it!
What we're looking for:
Real examples of design patterns that prioritise business metrics over user wellbeing.
The kind of stuff that makes you feel manipulated, confused, or trapped. Bonus points if it made you audibly say "are you kidding me?"
What happens next:
We'll review your submission, investigate the pattern, document the specific manipulation tactics at play, and (if it's sufficiently shameful) immortalize it in our Hall of Shame.
Every entry helps other designers, product teams, and businesses understand what not to do.
Submit your evidence below screenshots encouraged, rants welcomed.
