/* The Roblox Death Sound (alternatively known as Oof, labeled as Uuhhh in the official sound file, and other interpretations of the noise) is a short, one-second sound clip used in the MMORPG Roblox. Online, the sound effect is notably utilized in various fan remixes of existing scenes and songs from pop culture. Today $OOF lives forever on the Ethereum blockchain - 0/0% taxes - LP burned - Renounced - 2005 beta release of Roblox, the death sound has remained a staple element in the game's 10+ year history.

Authorities in crypto world like 3ac, Voyager Digital, LFG and etc captured investors' fund and gave false hope and promise to them. Eventually they never fulfil what they promised. They lied. They fled. They failed. It's time for us to build a community in anarchy way. We hate authority, we as the initiator of the movement will not open any "official group". Instead, please feel free to open group(s) and send the link to @anarchyinitiator. We will announce it and let you control it.
