Here is an interesting bug:
2.) Open this link in a tab: https://duckduckgo.com/html/?kp=-1
3.) Search for a single word that is an expletive, such as "shit".
4.) Observe "No results."
Also, because I learned in the IRC channel, if you access https://duckduckgo.com/
EDIT1: I found this
duplicate post too, describing this problem in less detail.
EDIT2: I found another bug;
1.) Load up, https://duckduckgo.com/html/
2.) Search for: oh baby !safeoff
2a.) You can search for anything, but add "!safeoff"
3.) You'll be sent to: https://duckduckgo.com/?q=oh%20baby&kp=-1&kl=us-en
This would be very useful for those who are security and privacy conscious.Let Me DuckDuckGo That For You
