Attendee list scams

“We have your event’s attendee list.” No, they don’t.

Almost every exhibitor gets the email: buy the full delegate list, with contact details, at a special price. Most of these lists are fake or scraped. Some aren’t. SummitShield helps you warn exhibitors and spot a real leak.

How the scam works

It usually goes like this

The pitch

“Verified delegate list”

12,450 contacts, today only.

The sample

A few real-looking names

Often scraped from a public page.

The payment

Paid upfront

For a list that’s useless, or never arrives.

The damage

Your name on it

And exhibitors who think you sold their data.

Red flags to look out for

If you see any of these, stop and check before you pay or reply.

  • An offer to sell your attendee or exhibitor list
  • A suspiciously exact number of contacts
  • A sender with no link to the event
  • Pressure to pay before a deadline
  • Nothing on the event website about it

Questions people ask

Are event attendee list sales a scam?

Unless the organiser is selling it, yes. Organisers rarely sell attendee lists, and data protection law limits what can be shared. Most offers are fake or scraped lists.

How do I know if my attendee list has leaked?

Plant made-up contacts in every list you share. If one is contacted, you know the list leaked and exactly which copy it came from.
