“4,560 signups in four weeks. Only ~730 were real — the rest were fake accounts farming free AI credits. DataCops flagged the linked clusters at signup, with enough context to act on. We didn't have to guess anymore.”
Stop Fake Signups BeforeThey Cost You Money
Every fake account that slips through costs you real money: wasted trial credits, inflated CAC, polluted funnels, and broken deliverability. SignUp Cops detects bot registrations, disposable emails, and repeat abusers in real time before they enter your database.
IP Service
Classifies network origin — VPN, proxy, datacenter, residential
Browser Fingerprint

Email Validation
Domain reputation, auth config, username pattern analysis
CAPTCHA was built for a
different internet.
Humans are committing the fraud.
Click farms pay real people per signup. Multi-account abusers run free-trial loops with burner emails. CAPTCHA was never built to stop a human who intends to cheat.
99.9% of CAPTCHAs solved by bots.
AI models crack image and audio CAPTCHAs automatically. Solving farms charge fractions of a cent per solve. The arms race is over. Attackers won it years ago.
CAPTCHA asks the wrong question.
Passing a CAPTCHA proves one thing: someone clicked a checkbox. It says nothing about whether the email is real, the IP is a proxy, or the device has 14 prior accounts.
It punishes real users, not fraudsters.
Friction from CAPTCHA causes real users to abandon signups on mobile at the worst moment. Meanwhile a determined fraudster has all day to click checkboxes and never gives up.
The crisis fake signups
quietly create
Free Trials &
AI Credits Burned
One abuser behind 500 throwaway signups drains your free tier and burns LLM credits before a real customer arrives.
Inflated CAC,
Wasted Ad Spend
Ad platforms optimize toward bot conversions and keep pushing budget at the same fake sources while your real CAC climbs.
Deliverability
Collapse
Emails to fake addresses bounce, hit spam traps, and burn your sender reputation, so real users stop receiving your messages.
False Growth,
Bad Decisions
Signup charts trend up while activation, retention, and revenue stall, so your team makes calls on numbers that were never real.
Detection stack

Our own dedicated IP intelligence system
We track ~6 billion IPs globally across residential, datacenter, VPN, proxy, and Tor networks, updated continuously so fraud can’t hide behind a rotating exit node.
- VPN IP tracking
- Datacenter IP tracking
- Proxy & Tor network tracking
- Full global residential IP coverage
- 350+ continuous monitoring points
Most cloud IPs aren't running people. They're running bots.
Click farms, headless browsers, and credential stuffers run on datacenter IPs, mimicking real human navigation to fool standard analytics. We index 146 billion of them, plus 200B+ residential and 12B+ VPN endpoints, in one live database.
IPs and network ranges tracked across IPv4 and IPv6, updated live.
Real human traffic. What your actual customers look like.
Every server-based bot, scraper, and crawler, fully indexed.
Hidden traffic, surfaced. Including private-relay networks.
Open proxies, Tor exits, and evasion infrastructure.
Disposable and high-risk domains. Fake signups stopped at the door.
Built for dedicated deployment.
Updated continuously across thousands of data sources.

FAQ
CAPTCHAs are a hard gate that tests whether a browser can solve a puzzle. They frustrate real users and still get bypassed by fraud-as-a-service farms. DataCops works differently: we hand you the full identity data for every signup (risk score, device fingerprint, IP classification, email reputation, linked-account graph), and you build the gating logic at your app level. Instead of slamming a block on a suspicious user, you can welcome them back to their existing primary account, add a step-up verification, or quietly route them to review. You stay in control of the user experience.
