[2020] Is there really nothing to do for these toxic players ?

Post has derailed from the initial discussion. That said, I will be locking this. 

For the main question of the OP, such things are not available for reporting or reviews. We actively get reports from staff members about names and we take care of those on a small scale but nothing in a major report process manner. This is also more complicated than a simple action. Imagine the review process, the appeal (because who knows what led it to this) and also legal aspects of it after user is banned/suspended. 

Simple solution is, do not add random people, ignore and more on. This is more of my personal suggestion and knowing how the internet can be, you simply cannot fight it.
