Is posting photo of my friend with his consent to our groupchat banneble?

Hello,

 

so recently my accout got disabled for "Sharing or parcitipating in sharing personal info".Only thing i remember doing was day before my account disabled sending some photos of my friend that he allowed me to send to our groupchat. Discord is not replying to my emails or DMs on twitter (I'm not spamming them, I sent like 2-4 emails). I also read the ToS and found almost nothing about this.
If there's anyone (or even a staff) reading this and being able to help me I would appreciate that.

Thanks
