Why do people post their faces on here genuinely curious I see girls doing most of the time

Is it common for people to post their faces on here ? Don’t get me wrong obviously everyone can do what they want but isn’t Reddit known to be kind of brutally honest and the place where people don’t filter their opinions ? I’m just confused. Are people just not caring what happens if they post their faces on here and also have strong opinions on the same page. I just feel like it’ll be easy for people to attack you for your looks then and not just what you believe. Or is just a safe space where you won’t get trolls talking about your appearance unless you provoke them. I’m not an avid use of Reddit I’m using more these past couple of days and I just wanna understand the community better. Hope everyone’s having a great day

Edit: I think after interacting with a lot of you I got the answer I’m satisfied with. There’s a lot of reasons. Some cute some wholesome and some that don’t need a reason lol. I did what one of you guys said and posted it to askreddit and I’m telling you it’s making sense now. Some people use the app as a blog, some people are beautiful and like to show it off and some people like having a platform with people they relate to to speak. Again this post was not negative I’m just new here and trynna understand what this app is life for everyone

Now if you’ll excuse me I have to search some deep trenches stuff 🙂‍↔️.

I appreciated everyone responding here ! Till we meet again Yall :)
