My incoming links do not make sense

on my new site, islandjay.com, I noticed that I have incoming links in my WP dash of course. However, they are all jibberish or related to coding sites that offer advice. Not one that I see when I click on has any connection or link to islandjay.com

Should I be concerned or did I somehow get these funky links due to some sort of plugin?

Thanks!
Jason
