It returns you a random server with port 80 or 443 open.

Just 80, it seems https://github.com/caioluders/server.casino/blob/354cec4c053...

That probably increases the odds that the servers it finds are "interesting"

Not really.... almost all web servers with 443 will have port 80 open to function. Current browsers all still hit 80 first.

Not before you push the button on the page though.
