There are a number of malicious websites which look similar or identical to Cardano.org. These websites have a scam giveaway. IOHK, the Cardano Foundation and EMURGO will never give away ada or anything related.
For the Telegram users among us, you are likely to be added to a malicious Cardano group which directs you to these malicious websites. Please feel free to use this walkthrough to prevent being added in those groups:
1- In your Telegram go to Settings
2- Select Privacy and Security
3- Select Groups & Channels
4- Under "who can add me to a group chats" select My contacts
Please read this Safety and Scam Awareness Article I wrote to help you avoid scams. Everyone is vulnerable to scam.
