This mods allows players to configure in which dimension should mobs from a specific mod not spawn.  
It works this way  
It creates a config file every time you create a new world, located in yourmodpackname\saves\worldsname\serverconfig  
the file is called youdontbelonghere.toml.  
It has "Blacklisted Mods", which contains the mods that will be removed. You must add mods there in the following way:  
"modid1,modid2"   
Whitelist will cause a change in how the Blacklisted Mods is treated, instead of banning mobs from the dimension list, it will cause to only allow them in the dimension list. By default its set as false.  
Dimensions contains the list of dimensions in which mobs will be banned from spawning. If Whitelist is set to true, it will cause to remove mobs from any other dimension that is not in this list.  
Also if whitelist is set to true, mobs from the Blacklisted Mods will naturally spawn in the dimension  
Blacklisted mobs list wont spawn naturally. (useful to avoid bosses naturally spawning)  
Weight controls how often entities should spawn.  
  
Warning: do not use minecraft in the Blacklisted Mods since it will probably cause a crash. This was intended to work for mods only.
