If you’re using something like tor, and rotate on every single search, then that would be ideal.
I assume you’re not using tor. That means all your searches can still be linked to you via the network source (ip address, etc.). Google can also use your search patterns to fingerprint you.
I wish we had a nice tagging system (and I don’t think they should be hashtags) that was also in common use.
I want to be able to search any post related a certain topic, and sometimes, these may not always be in that topic’s community, because topics can overlap. For example, I might want to read posts about Ukraine war, but those might be in world news, US news, or combat footage communities. Could be a community about Ukraine in general, or Ukraine war specifically.
I also may not want to get it from a single Ukraine community. Maybe by finding posts with the “Ukraine war” tag, I’ll see several communities and join the one I want. But there needs to be a way to group them somehow.
Such a tag system may be useful for combined topics. For example, I may want to look for posts about music software. They might not be common in the music community, or software communities. But I could filter by both tags and find what I want.
