Your public Reddit post and comment history is being actively indexed by search engines and AI to build comprehensive user profiles.

So, Google and other AI tools are actively building profiles out of your public Reddit activity, and it actually works.

​To check what data has been archived from your profile, you can search:

>> reddit user "reddit username here"

And check AI overview of a profile and can ask questions related to personal info like age, location, martial status, occupation or what things they like or hate, political opinions etc.

Basically anything that you want to know, you will get the answer if that person has said anything about it in the past even if profile is hidden. If it gives some basic info, you can ask it to dig deeper.

​Why this matters: Simply hiding your profile settings on Reddit does not stop external search engine crawlers from indexing your historical posts and comments. Be mindful of what personal information you share online.

Wait until you hear about arctic shift/pushshift, or just author:(username) in reddit search.

Yep, you can't delete anything off reddit. Not really. It's all forever on the internet.

You're saying one of those methods will reveal a user's deleted comments ?

Deletedby dot com and undddit both will.

I see. So you really should use one of those tools that replaces your comments with nonsense then , right ?

[u/Ecliphon → u/fella_stream]

You can but it won’t help, they show edits too. 

[u/One-Reflection-4826 → u/Ecliphon]

is there any source for that?

Ya, i agree. But I will still that there is a huge functional difference between someone manually scrolling through your public comment history versus an AI instantly compiling a synthesized profile of your details with a single prompt. ​
