I think you misunderstand, OP is purposefully adding "site:reddit.com" to their search query, to only get results from Reddit. Google isn't adding it for them.
I do this sometimes too, because it's one of the ways to get actual opinions on something, and not just worthless blog spam.
Oh, that makes sense.
OP is adding `site:reddit.com` to tell Google to find results from reddit instead of elsewhere. If their workflow is like mine, it goes 1. enter search, 2. get frustrated with spammy / marketing / ad results, 3. limit to reddit, 4. find thoughtful human with genuine answer / feedback.

If Reddit were higher in their search rankings, they wouldn't need to add site:reddit.com to their search words.
I also find searching Reddit, especially for introductory advice, to be very commonly useful. Since Reddit's search sucks, I usually use duckduckgo or Google to search it.

I think it would be worth investigating on your part as well. Next time you do a Google search that will be heavily populated by blog spam and listicles, append “site:reddit.com” to instead get long user-rank-sorted discussions among actual human beings.
That seems strange to me. Most of my search results don't lead there. This seems like something worth investigating on your part. Maybe google knows you like reddit, tend to follow links there, and hence puts them higher in your search rankings? Is that a thing with google? I think it may be based on my own past experience too.
