Block Hub · Red Flag Checker
Is this a scam?
Two minutes. We'll show you the red flags. We never say "safe", because new scams appear every day.
How Red Flag Checker works
- Pick what’s happening. A message, a call, an offer, a website or a person you met online.
- Answer a few yes/no questions. About how they contacted you, what they want and how fast they want it.
- Read your red flags. We show every red flag your answers match and why it matters, with what to do next.
- Check the link, address or username. Paste it in step 3. Links are checked against phishing lists, look-alikes and website age; members can also check wallet addresses and usernames.
- We never say “safe”. New scams appear every day, so no red flags doesn’t mean it’s fine. If in doubt, stop and check through the company’s official app.
- Your answers to the questions stay in your browser. Anything you paste in step 3 is checked and then forgotten: never saved or logged.
