Many people who have accounts on the blockchain-based virtual world Decentraland (DCL) have received the following direct message from Discord this afternoon. It claims to be an official bot called Decentraland Announcement, informing users that there is a brand new version of the DCL client which can be downloaded. THIS IS A SCAM! DO NOT VISIT THE ASSOCIATED WEBSITE, OR INSTALL ANY SOFTWARE. Decentraland remains a web browser-based app; there is no separate client for you to download.
Here is what the scam notice looks like, so you will recognize it:

This is a prime example of how scammers use social engineering tricks to try to separate you from the cryptocurrency in your wallet. Be warned and stay safe! It took me about half a minute of reading to realize that this was a scam (the website URL, which I have blurred out in the image above, was a major red flag to me).
I leave you with the final, authoritative word on the matter from DCL employee Sam Hamilton, a.k.a. toonpunk, who posted to the official Decentraland Discord server:
Decentraland News is a scam, they have been banned but if you have a message from them do not click any links.
