These are all automated bots. No one is “bothering”. You open the 3 most well known ports you’re going to get connections. They don’t know what you’re running nor do they care.
By the way, I find it annoying that my logs get filled with this kind of trash. It has the perverse effect of making me long for something like Google Analytics since they rarely if ever bother running a javascript runtime.
If you put your ssh server or something on an uncommon subdomain how will these scripts find it?
If you are on @ or some common name sure, otherwise no.
