Into what? I mean, the website is an empty shell. You don't spend 500USD into Bid Bot for just two PDF and not a single line of code.
For example, they claim that Ezira will, I quote,:

EZIRA brings your content to life:
Share any files with the world by posting them to EZIRA, and earn rewards.

You can't freely host, share files and get rewarded to do that. You'll need tons of servers hosted everywhere in the world, and even in a decentralyzed way like IPFS ( https://ipfs.io/ ) you need to pay to host your files, nobody will host your files for free.
