"Startpage, the world's most private search engine"
...or maybe not? Despite their "no logs, Nada, Zilch, Zero" policy, I've found something contradictory to say the least.
Try to change the HTTP useragent header/string of your own browser to an empty one or replace it with a single random letter such as a space, and then perform any search with Startpage or Ixquick
The result is this error message:
"You may be using a privacy-oriented browser extension that conflicts with Startpage. Please disable this extension and try your search again. If this does not help, please contact us at (212) 447-1100 (USA) or autoquery @ ixquick.com."
Why the search engine doesn't let me perform searches if my UA is empty, and why is it checking what my UA is in the first place? Needless to say that DuckDuckGo doesn't have such limitation.
I've asked for an explanation through email, but no answer was given to me in more than a week.
Hey DDG, now you can use this info to shit on Startpage's face every time someone tries to say that it's better than The Duck. Lol.
