The ADA lawsuit industry, Part 3: Prolific testers and litigation mechanics

The "prolific plaintiff" dynamic is less about personalities and more about process. High-volume accessibility litigation behaves like an operating system: repeatable discovery, repeatable pleading, and repeatable settlement mechanics.

What Concentration Changes

When filings concentrate in a relatively small set of law firms and repeat plaintiff networks, defendants face a predictable cycle:

• similar issue classes recur
• similar legal framing recurs
• similar economic pressure recurs

That predictability is uncomfortable, but it is also actionable. If the failure classes are repeatable, they are preventable.

What Defendants Should Do Differently

• prioritize elimination of recurring low-complexity defects
• maintain centralized records for prior claims and remediations
• align legal and engineering response into one workflow
• verify closure with both automated and manual checks

This is how you reduce re-targetability over time.
