Notice

Dear website visitor,

We hope your preparations for the upcoming Congress are going well.

We would like to make you aware of a recent issue concerning fraudulent emails offering to sell delegate or attendee lists for our event. These messages are not legitimate and are in no way affiliated with the Congress or its organizers.

Please note that the Congress will not be providing or selling a delegate list, and we strongly encourage you to disregard any unsolicited emails making such offers. These emails are typically sent by unauthorized third parties and are considered spam.

If you have received one of these emails, we recommend that you:

  • Do not respond or engage with the sender.
  • Do not click on any links or download any attachments.
  • Report the email as spam, if possible.

The privacy and security of our attendees and partners are a top priority, and we are taking all appropriate measures to address this matter.

Should you have any questions or concerns, please don’t hesitate to reach out to our team directly.

Thank you for your continued support, and we look forward to welcoming you to the Congress.

Warm regards,
IAC 2025 Congress Managers
