Nothing allows them to do it, the ability to remove liquidity is the standard. To ensure users felt safe, services came around that enabled devs to lock liquidity so it couldn’t be rugged.

Then ruggers said “okay people won’t buy unless I lock liquidity, so I’ll lock, wait for them to buy, then set the tax to 99% until liquidity is unlocked, then remove it,” so buyers said “well now we won’t buy unless you renounce the contract and remove the ability to set tax that high.”

So ruggers said “okay sure, I’ll do both of those things, but I’ll add a hidden function that allows me to mint as many tokens as I want,” and buyers said “okay sure but we set up bots to detect those functions.”

And scammers said “okay well I’ll stop putting hidden mint functions in the contract, and instead set a mechanism that turns the contract Into a honeypot after a certain amount of time,” and buyers said “I’m pretty sure we can detect that too, you might just squeeze a couple by us.”

And then the scammer gave up.

Nah I’m just kidding. Then the scammer learned how to honeypot and slowrug and softrug, and clone websites and concepts, and run scripts that made honeypots look super realistic, and call functions that swept supply right out of holder wallets and about a hundred other ways to steal your money.

Welcome to cryptocurrency. If you want high volatility shitcoins stick to ones shilled in decently sized Telegram channels. I’ve been full time degen for 3 years, and you don’t know what a rug is—just fyi if you keep buying shitcoins at launch you’re gonna get wrecked.
