Unknown scammer
Preserve the evidence, protect accounts, report the contact, and avoid promising yourself a settlement where no responsible, reachable party can be identified.

How to Sue Robocallers and Spam Texters
You usually do not begin with a lawsuit. You begin by preserving the contact, determining whether a reachable business can be connected to it, organizing the evidence, and giving that business a fair opportunity to investigate and resolve a documented demand.
This is general US educational information—not legal advice, a finding that a violation occurred, or a promise of payment. Rules, courts, deadlines, exemptions, consent issues, and state law vary.
Start with the hard truth
The number alone usually will not identify the caller
Caller ID can be spoofed. Numbers can be reassigned, disposable, or rotated across campaigns. The more useful clues are often the seller, offer, URL, callback number, voicemail, transfer destination, payment recipient, and statements made by a representative. Some anonymous or foreign scams will never present a practical private-recovery path.
Identifiable business or seller
Document the connection, consent history, opt-out requests, contact chronology, and supporting records before making a demand for resolution.
The practical path
Document first. Demand resolution. File only if necessary.
Classify the call or text
Separate sales calls, prerecorded or artificial voices, marketing texts, post-STOP contacts, Do Not Call issues, account messages, political or charitable contacts, debt collection, and anonymous fraud.
Preserve the original evidence
Keep complete threads, logs, voicemails, screenshots, opt-out records, consent records, URLs, offers, and a chronological contact table.
Look for the responsible business
Investigate the seller benefiting from the solicitation without assuming that the displayed number, carrier, or lead generator proves responsibility.
Evaluate the facts cautiously
Consider consent, exemptions, business relationships, the communication’s purpose, the governing rule, state law, and what the evidence can actually prove.
Send a documented demand
State the facts, attach an organized event log, explain your position, propose a supportable resolution, and preserve proof of delivery.
Negotiate in writing
Review any identity or consent evidence the business provides. Keep offers, releases, correspondence, and payment records with the original evidence.
File only as a last resort
Before filing, reassess the defendant, evidence, forum, arbitration, jurisdiction, deadlines, costs, service, defenses, and whether legal advice is appropriate.
No product required
You can do this manually
Use a spreadsheet for the contact log, folders for original evidence and exhibits, public business records for identity research, certified mail or another verifiable delivery method, and the current forms and rules published by the court if filing eventually becomes necessary. CallSlayer is optional; the instructions in this guide do not depend on it.

Real people and reported outcomes
See how consumers documented calls, made demands, and pursued cases
These accounts make the process concrete: identify the business, preserve the chronology, make the dispute understandable, and decide whether a demand or filing is justified. They include settlements, default judgments, an arbitration award, and sustained repeat litigation. Each is an example—not a promise that different facts will produce the same result.
$1,200 negotiated settlement
David Weekly traced a spam text through its linked domain
VICE reported that Weekly identified the company behind an insurance text, filed a TCPA case, and negotiated a $1,200 settlement after the company was served.
Why it matters: The useful clue was the business behind the linked domain—not merely the sending number.
Read the VICE report$3,500 reported settlement; later class action
Thomas Buchanan began with a spreadsheet
CBS Texas reported that Buchanan logged calls, dates, and numbers, obtained a reported $3,500 settlement in one matter, and later became the named plaintiff in a much larger Sirius XM class action.
Why it matters: His account illustrates disciplined logging and the difference between an individual dispute and class litigation.

Dan Graham repeatedly pursued identifiable telemarketers
FOX 26 and Chron reported that Graham documented calls, identified the sellers, pursued dozens of matters, and said his gross results exceeded $100,000.
Why it matters: This was a sustained, time-intensive practice—not the expected result of one ordinary demand letter.
Read the FOX 26 Houston report$60,000 default judgment
Ursula Lenhardt represented herself in a robotext case
KCUR reported that a federal judge awarded $500 for each of 120 texts after the defendant did not respond. The judge rejected her additional and enhanced-damages requests.
Why it matters: A default judgment is a particular procedural outcome and should not be treated as a prediction for a defended case.
Read the KCUR / Kansas News Service report$459,000 reported judgment
Veronica Davis documented hundreds of calls after asking that they stop
Patch reported that Davis sued after more than 300 automated calls connected to a furniture purchase continued and a court ordered $459,000 in damages.
Why it matters: The scale, existing customer relationship, repeated stop requests, and extensive record made this unlike a single anonymous scam call.
Read the Patch report$300,000 arbitration award
Paul Demuth preserved repeated stop requests
WTAE reported that an arbitrator found 200 unauthorized robocalls were made knowingly or willfully after Demuth repeatedly told the caller to stop.
Why it matters: This was an arbitration award involving a known creditor and recorded stop requests, not an anonymous telemarketing number.
