GF and Snapchat

So I went through my gfs snapchat and she had chats that were received from around three weeks ago from a couple dudes. Upon going through the chats i see that they saved her snaps like 2 months before we stared talking (so roughly 7 months ago) . She told me she used to be a “snapchat hoe” in the past. I would like to believe that they slid up on her story and she just left them on opened. Although it bothers me that even though she left them on read, they still have thirst traps sent in the past. Would it be too controlling for me to ask her to unadd them?

UPDATE: asked her to remove them because it makes me uncomfortable because of her history with them and she was completely fine with that.
