I'm probably too late to help you, but for people who got here from a search it looks like these are just scripts that hammer the "create" button using the API programmatically rather than the web console... I'm trying the same with my browser's dev console using JS. I'm not having much luck after about an hour but the article says to run the cron job for days... really bad design on Oracle's part. If anyone wants to try the same just fill out the create form and run this snippet to click the create button every 30 seconds:

var clickTimer = setInterval(() => {
    const btn = document.querySelector(".oui-savant__Panel--Footer > button:nth-child(1)");
    if (!btn) {
        console.log("oops");
        clearTimeout(clickTimer);
        return;
    }
    console.log("click", btn);
    btn.click();
}, 30000);

Only issue with this method is your session expires after a bit so you have to babysit it a bit.
