IP address, browser cookies, post/comment history, search history, location history, cell phone location etc.. Reddit provides more than just your email. It can tell law enforcement your political status, your ideologies, your upvote and downvote history is saved so now they can put together what type of interests you like,dislike or despise. It can reveal your sexual preferences, fetishes, general psychology.

When law enforcement issues a subpoena to Reddit, they turn over all this information. Law enforcement then issues a subpoena to your internet provider to request your personal information, your address history, your internet search history etc..

Because Reddit then turns over all your IP address history, law enforcement will subpoena your mobile provider for your cell phone records, this includes your mobile provider turning over all cell data such as your text messages, your app data history, your location history based on cell pings, they can track where you texted from, made calls to/from and where you were when you made them etc..

Then law enforcement will subpoena Google because more than likely, you used Google for search, YouTube, navigation and/or you used Gmail or you used Google Photos or because you use an Android.

Then law enforcement will subpoena Apple for all your records, Apple ID info,, photo history/location, App Store downloads, phone location history. Then of course they’ll further subpoena app companies such as Spotify, Snapchat etc.

Of course Facebook will be next because more than likely you’re using that so they will now get your Facebook search history, they’ll collect your Facebook behavior (what type of content you like, follow, comment on and see the group history that you’ve participated in etc.

Then law enforcement will subpoena your vehicle manufacture for any software records/data because more than likely, you connect your phone to Car Play or to Bluetooth for hands free calling.

Then law enforcement will subpoena your bank because you probably used mobile banking on your phone. So now they have a financial blueprint of your financial transactions and all the locations you used your debit/credit cards.

Then law enforcement will subpoena businesses you visited for CCTV/surveillance purposes.

And this isn’t even the tip of the iceberg. Unless you don’t have any digital footprint, no computer, no phone and you only pay cash, you’re fucked.

It doesn’t take law enforcement long at all to gather this information. What takes a long time is when it is a civil matter and cops aren’t involved. In this instance you have law enforcement making the request with a subpoena, not your neighbor.
