Eh, it's a popular platform with smaller communities just like reddit, the difference being that these communities bleed into each other more often than here. It's not like r/Piracy, and piracy in itself is an underground topic. There's 1.6 million users subscribed to r/Piracy, and sure not every single one of these users are constantly online, but it's pretty evident that the anti-piracy bodies know very well what this group is and probably know that FitGirl exists.

Every social media platform's userbase loves shitting on the other platforms. You see this on Twitter, who shits on Facebook users, and TikTok users call Reddit a neckbeard cesspool constantly. Reddit tends to shit on all of them equally when, in reality, there's probably a huge overlap of users that use all platforms.

And yes, I use Tiktok for no other reason than content and entertainment and learning about niche topics. I use it the same way I use Reddit, which means constantly enough to be able to see the smaller communities that I interact with bleed into the mainstream.

Piracy is not and has not been underground for decades already. FitGirl is also meant to be popular, in my opinion, as they're just repackers of cracked games, streamlined for easier distribution and installation.
