NRDM is an abbreviation and or acronym used by cryptocurrency fanatics, fans, and DeFi users who have frequently made uncanny and clever observations, that sometimes the sacrificial lamb is one's own kind, when it comes to phishing links and scammers that target their foe through Direct Messages sent via Telegram or Discord Channels, or generally baiting their foe online.

The sacrifices of these sacrificial lambs, has resulted in the social phenomena The Distribution of Clever Abbreviations (DCAs or DoCAs) to help remember that, one should always be weary of suspicious Direct Messages that are sent to us online, especially when they are shrouded in the veil of unparalleled kindness or desires to be helpful, followed by a very odd link that should have otherwise screamed "NOOOO - Don't Click Me!! ( DCM ) --- if it were not for the HTML Link & the oddly familiar sense of safety given the impression of the link & underlining, bringing you quickly to the end of the road for your money, as it connects to a scammer or fraudsters server & database, and quickly sends them all your personal information & access codes, in the blink of an eye *Poof* all gone.

One must find ways to aMUSE one's self with these things, lest we never forget, all the sacrificial lambs of our time. Amen.
