* -> What?
* [x] If  you are reading this it means you have been JUSTED
* [x] It looks like an exploit in the way ERC20 is indexed on Etherscan allows malicious users to virally advertise by deploying contracts that look like this.
* [x] You pretty much own this token forever, with nothing you can do about it until we pull the UNJUST() function.
* [x] Just try to transfer it away, we dare you!
* [x] It's kinda like shitposting on the blockchain
* [x] Pls fix Papa Vitalik
* [x] Also we love your shirts.
*
*
* Also we're required to virally advertise.
* Sorry its a requirement
* You understand
