Program to repeatedly crash realms

Hi, So recently I have seen a few discord groups dedicated to destroying realms. (I can provide you with some discord users and servers if needed)

A few of these groups use a program which allows them to input the realm code and then the program will crash the realm over and over preventing anyone from joining.

They do this by getting the realms IP and then repeatedly send crash packets to it.

I believe that this is quite a significant issue that needs to be addressed as people are paying for these realms just for them to be taken down so easily, with some putting hours and hours of work into their realms.
