I think everyone gets those *Like* bots. I just ignore them. The links are for paid promotion deals (I know because I clicked on a couple of them), which you can also safely ignore. It all sucks but it's part of what we have to put up with on the internet these days.
Not a stupid question at all though. Feel good that you are uploading your own music and have fun!

Does SoundCloud not have a way to report them? (genuine question as I've never actually looked)

Thanks for answering. Would also be interested in a report button.

You can block them and report them as spam.
