What Is Dark Patterns Hall of Shame?

Updated

Dark Patterns Hall of Shame (hallofshame.design) is a website that documents real-world examples of deceptive and manipulative user interface designs — commonly called "dark patterns" — so that ordinary users and designers can recognize them and avoid being manipulated online. It works as a running catalog of case articles, each naming a specific company and the pattern it used, from pre-checked consent boxes to deliberately difficult cancellation flows.

What the site covers

Each entry on the site is a short case write-up. The homepage presents them as a feed of posts, each tagged with the type of dark pattern involved. The patterns named in the site's own headings and excerpts include:

  • Preselection — options that are already checked or enabled by default, so users opt in without noticing.
  • Privacy Zuckering — designs that push users into sharing more personal data than they intended.
  • Trick Questions — wording or layout that makes a form answer mean the opposite of what the user expects.
  • Roach Motel — a service that is easy to sign up for but hard to leave.
  • Obstruction — deliberately adding friction to a task the company doesn't want you to complete.
  • Misdirection — drawing attention away from the choice that matters.
  • Cookie Wall — blocking access to content until cookies are accepted.
  • Nagging — repeated prompts to do something the user has already declined.
  • Fake Scarcity — manufactured urgency or limited availability.

Who it's for

The site is written for two overlapping audiences. For everyday users, it functions as a warning list: if a company you use appears here, the entry tells you what to watch for and, in several cases, how to opt out or cancel. For designers and product people, it works as a reference of patterns to avoid, with each case showing how a specific design choice crosses the line from persuasion into manipulation.

How to use it

  1. Open hallofshame.design and scan the feed for a company or product you use.
  2. Read the case to identify which pattern is involved and what the deceptive mechanic is.
  3. Where the entry covers a setting or subscription (for example, AI training opt-outs or a cancellation flow), follow the described steps to change your own configuration.
  4. Use the pattern names — preselection, roach motel, nagging, and so on — as search terms when you want to check whether a new service uses the same tactic.

The site's stated purpose is to help people protect their online privacy and rights by staying informed about these designs. It is a documentation and awareness resource rather than a tool that blocks or fixes dark patterns for you.
