My steps for this report:
- I created a .onion domain
- I kept it hidden to Tor (without wiki publishing...)
- After that, I created in that .onion domain one static web page: Gray background and only one "post" box like Google search webpage.
- I Put a little tittle: "search engine" or similar
- And I "Logged" the words in the search box.
- Now we had to wait... exactly 6 months.
This is the result:
Welcome to TOR top-search-words. Oh my...!
