Reviewing my logs, I found this odd request:

GET /infocon.htmlppQ/detail/20130403164740572kode-til-boozt-10/basura-que-va-acumulando/_medium=twittersideIM&lang=en&brand=nokiaokseen-fortumin-joensuun-voimalaitokselle/)&utm_term=inspirationfeedistan%20Tehreek-e-Insaf)%e0%b9%89%e2%86%90_%c3%96k%e2%98%bc%e0%b9%84%e0%b8%a1%e0%b9%88%e0%b9%84%e0%b8%8a%e0%b9%88%e2%99%a5His%c3%b6%e2%86%94ll%e0%b8%95%e0%b9%88%e0%b8%81%e0%b9%89%c3%b6%e0%b8%a1%e0%b8%b1%e0%b9%88%e0%b8%a2%e0%b8%94%e0%b9%89%e0%b8%b2E%e2%86%90n%c3%96%e2%86%90m%c3%96neY%c2%ae%e2%97%84%e2%97%84--html26eu1=0&eu2=0&x=50&y=16&dataPartenzaDa=20121001&dataPartenzaA=20121010&orderBy=Prezzo HTTP/1.0" 302 154 "-" "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)" "2a03:2880:20:4ff7::"

It does look like a valid request from Facebook. "facebookexternalhit" is used by Facebook to screen links people post for malware. However, the link "doesn't make sense". Doesn't really look like an attack to me, just weird. Any ideas how this may happen?
