In the last couple of months I have noticed an increasing trend of supplying me search results that are completely unrelated to the current query and tie back to my location or previous searches. I can say this with a high degree of certainty this is without a doubt beyond the 100th instance this has happened.
My browser is configured against tracking and fingerprinting (in fact all my devices are) which would make it fairly difficult to retain any data unless they are profiling me.
I also returned totally accurate results using the exact same query. I would really like to know what is going on here. This is a common complaint with some people using DDG, that the results are poor, but I consistently have as good if not better results than using Google.
