My girlfriend has decided to stop following certain people on insta, but why do I feel bad about it?

Anonymous
So quick back story, my girlfriend and myself agreed not to follow models or certain people on insta who do anything sexual. As it just causes issues in relationships and makes the partner feel bad about themselves. She has felt the same having a boyfriend in the past who followed prnstars and models.

Fast forward and she hasn't gone through her list and unfollowed previous people, before you say anything we follow each other on insta as she would like to and I would, rather than just not follow each other. I got recommended additional friends who she followed, one of which was sexual and made me feel uncomfortable and the other of course random guy showing off his pecks in almost every photo which just made me feel bad (yes I know insecurity I probably have to work on)

Either way we are good at communicating, I explained and she said she sees why it would make me feel that way if she was in my shoes and I was the one following models etc. Said it was old accounts and that she wants to go through them with me and delete them. I have to admit I have the most amazing girlfriend and glad she is happy to do this.

However at the same time, I don't know I feel kind of bad as it is her insta account, I told her it's just a problem with my insecurity, obviously not her fault in anyway at all and she isn't obliged to, she just told me she would feel the same, loves me and is happy to do so.

Is there any reason I should still feel slightly bad about it? Or just be happy I've got an amazing girlfriend and just let it happen?

Just posting an update, Insta screwed up and turned out he was just following her. She explained she used to date the guy and dated him for a couple of weeks but he was mean, possessive and even flew to England for 5 days to ask her daily to be his, took photos while he was there posted them on insta, and even with his new girlfriend seems to be stalker my girlfriend on insta, she didn't realise he was following her again, as its a different account and blocked him
