If anybody ask, it's not me who said it, but you can also easily use Shodan to find a lot of open Bitmagnet instances. Many people who self-host do not seem to be aware of the “questionable” decision of docker to always listen on 0.0.0.0 by default and make a firewall rule to expose your service to the entire web (you can also find instances of jackett and some *arr stack, but most of them are at least password protected).
