Getting a lot of porno search terms

Hello everybody,

Since a couple of days I get a lot of traffic from Indonesian ‘porn’ terms.
Like:
bentuk memek karena tidak pake cd, foto cewek cantik ngentot, celana berbentuk memek, hencet, gambar dan gaya ngentot cewek bispak

I don’t know where its from, and don’t know how to get rid of it.
Anybody can help me?

Thanks in advance.
