From the source
At Replit, we have created a general purpose computing environment that anyone can use to run whatever programs they want, and access whatever services they want.
You can run almost any type of software in a repl, including Mac OS , a Commodore 64 emulator , DOOM , or even a web browser.
While this is powerful, it poses a few problems for us.
There are some types of programs, like cryptocurrency miners and spam bots, that either use too many resources or damage the community as a whole, and as a result we can't allow them.
This is especially important considering that a substantial portion of users on Replit are teenagers, many of whom use Replit at school or under parental supervision.
We want to continue giving everyone computing superpowers, while still finding a way to protect our users from inappropriate content.
That's why, starting this week, we are blocking all internet access to adult content and malware.
That means if you run a web browser on Replit, you won't be able to access any objectionable or NSFW websites.
How does it work?
We did this by enabling the use of Cloudflare's family-friendly DNS resolver by default in all user repls.
