some wordpress installations hacked?

Hello.
I noticed from the following google search (“ruby first second third fourth”)

https://www.google.com/#sclient=psy&hl=en&source=hp&q=ruby+first+second+third+fourth&pbx=1&oq=ruby+first+second+third+fourth&aq=f&aqi=q-w1&aql=&gs_sm=e&gs_upl=604l4005l0l4075l30l15l0l6l6l1l375l2239l0.4.6.1l11l0&bav=on.2,or.r_gc.r_pw.&fp=fe4d51c11f0a28fa&biw=1680&bih=928&safe=active

that my blog shows up in google with the following title: “Buy Diclofenac Without Prescription”

Anybody know what might be going on there?

As a side note, searching google for the phrase “Buy Diclofenac Without Prescription”

https://www.google.com/search?q=%22Buy+Diclofenac+Without+Prescription%22&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&safe=active
“Updating”

shows many other wordpress installations that have perhaps been hacked?
“Reinstall now” to 3.2.1 doesn’t seem to fix it. Or maybe it should? It’s hard to test since you have to wait for google to update their index.
Cheers!
