Today, a site was launched where you can download mods for Factorio in semi-automatic mode. You just select the mod, copy the link and insert this link into the download field on the main page of the site. While working on how not to catch the account's account factorio.com. A ban is very easy to catch, since there will be many requests from one account and it will look weird - why would someone download the mod several hundred times? This creates a heavy load on the portal databases.
There is an idea of downloading mods to a file sharing service, and further downloading from a file sharing service. Of course in automatic mode. But for this you need to know the file sharing API. There's still work.
