Admin of https://kglitch.social, an experimental Kbin instance.
The only time I use ddg is to find conspiracy sites to add to the blocklist I maintain. All the trash rises to the top in that search engine. It’s rubbish.
One nice feature of Kbin is you can block domains. So when I block rumble.com right after typing this, I won’t see any more videos from rumble in all communities.
Mostly to avoid conspiracies. The intended users are people who want to protect vulnerable family members.
Another purpose is to demonstrate that the big social networks could get rid of disinformation if they wanted to - “look what 1 person can achieve, in their spare time”, kinda thing.
