Realms Crash Major Issue

Hi,

I would like to report a major issue that has come to my attention. For the past month, I haven't been able to access my realm. This user has been DDoSing my realm with Microsoft accounts. I do not have any knowledge of how this is done but all I know is that he is using my realm id and auto-generated Microsoft accounts. I have 2000+ members on my realm and I wouldn't like to loose them! I have attached what the crasher looks like below and also what it looks like when I load into my Realm.

 

My Microsoft Account Name is: Zakleby

The realm id is: 6000240

The realm name is §l§d§•Galaxy PvP §0| §aOpen{}{}

Please get back to me as soon as possible, Thank you.
