Are these SSH passwords of hacked servers?

I have been seeing persistent SSH connection attempts on my computer from a familiar IP address. I got curious and decided to do some Googling on the IP address. Turns out that someone from Indonesia is publicly sharing a whole list of IP addresses of servers, some from Digital Ocean, with their SSH passwords. I am not sure whether these servers belong to that person, whether these are admin passwords and what is the purpose of the person sharing it publicly. But it does look shady since I am getting SSH login attempts from one of those IPs. Are these SSH passwords of hacked servers? Why is the person sharing it? What can be done about it?
