I found my dad’s Reddit account

Look I didn't go snooping, it was logged in on the family Ipad so let's just be clear about that. On mobile sorry for formatting

I'm 17F, and I have 3 siblings (15M, 13M, 10F) and two married parents, both 42.

I was on my families iPad watched a show and decided to play a game, so I opened safari. Just some dumb cool maths game brain rot type thing. To get there I decided to scroll the history to get back to the same game. And there was Reddit in the history. Now, I know my parents aren't really aware what social media is, like to the point they have a shared Facebook that hasn't been updated since I was 10, so I was a little confused.

I'm a nosy teenager so yes I clicked it, and boom, a Reddit is open. And it's got all these posts in parenting subs and at first I though "oh yeah that makes sense" then I actually read the posts and OH BOY that was not good. (Tell me you wouldn't have read it if you were me and I'll give you nothing for being a liar lol)

So in the posts (I'm going to be vague so no one finds it) there were our real names, ages, area that we live etc. that's bad enough imo but there was a bunch of shit that was just not true there. And I don't mean like "I was there and that's not what happened" as a teenager angry at their parents, I mean fully 110% did not happen.

And not just like silly stuff like I got my kid this thing (and in real life I didn't), I mean like huge "my daughter had a teenage pregnancy and miscarried" kinda huge. IVE NEVER EVEN DATED (fyi asexual so that's a no from me) like what is this??? Some sick role play??

Like it might not even be his, I have other siblings but it's from "my fathers real name and age" so I'm assuming it's him????

So do I just ignore it? Do I talk to him?? What do I do?? Help Reddit please

TLDR: found my dad's Reddit, may not be his, it's full of lies but also real details, what the f do I do???
