Mit jelent? Ismeretlen log bejegyzések

Átnéztem az apache logot, és találtam néhány számomra ismeretlen (beazonosíthatatlan) kérést.
Nyilván nincs baj, hiszen mind 404, igazából arra lennék kíváncsi hogy mi ez a: "Toata dragostea mea pentru diavola" meg hogy mit érdemes megnézni még ilyenkor. acces.log első átnézésre rendben van.

A konkrét kérések:
