🚨Important Community Security Reminder

With the holiday season upon us, we want to remind the entire Cardano community to remain vigilant. Historically, phishing attempts and social engineering scams increase during this time of year.

Please remember:
1. Verify sources: Only trust information from official sources.
2. Ignore unsolicited DMs: Admins and support staff will never DM you first.
3. No "Free" ADA: There are no legitimate events that require you to send funds to receive funds back.

Familiarize yourself with the most common scams by visiting the following website: https://cardano.org/common-scams

Stay safe and enjoy the holidays.
