Chances are you have an ISP that is doing dynamic IP. Clear cookies and cache on everything you ever touched Reddit with, note what your current IP is (Google “what’s my IP address”), unplug your ISP modem for about 15-20 minutes and plug it back in. You should get a new IP, check with the Google trick again.
Might get tricky if Reddit does something like a hardware ID on your computer or something, but I doubt it.
Kagis ok, it’s better than Google now, but not the Google of the past and only if what you were looking for is recent and indexed. If not, it just falls back to the same Google results. Good if you want separation and not having Google know what you’re searching for, but beyond that…meh.
