Strange link when check in Google Analytics


Today, when i check real-time overview on my website in Google Analytics, i see few strange links which come from some referrals site. Not sure if they're crawling my site or what does it mean?

e.g. one of their links is I tried to go to there for closer look but i don't see any link to my website.

Could you take a look screenshots then give me some advices?

Thank you,
