This isn't the first time it happens, so I thought I should let you know.
Searching with Google, I sometimes get links to OB, among others. When I click on the OB link in the Google result page, I land on a strange page. Example:
propagating dendrobium - Google zoeken
When clicking on this link:
Dendrobium Propagation I land on this page:
FileStore123.info - Your File Hosting .
If I click again on the OB link, it takes me to the right page (so there's a cookie involved here).
