$GATE - Keeper 🔒

Telegram has become a go-to platform for crypto enthusiasts, especially in the DeFi and 'Shitcoin' communities, thanks to its strong privacy and easy-to-use chat rooms. 

But here's the catch: as the bull run is coming up, more people are jumping into Telegram. This surge isn't just bringing in eager investors and crypto fans; it's also attracting a wave of bad actors. 

These troublemakers, ranging from relentless spammers to scammers, are getting smarter and more numerous, ready to disrupt our discussions and prey on the hype. As our groups get busier, these bad actors become a bigger headache, messing not just with the vibe but seriously threatening the security and trust within our Telegram communities. 

Now, more than ever, we need a rock-solid plan to keep these intruders at bay and maintain the integrity of our conversations.

That's where $GATE Keeper steps in.
