I found a player in my server who was using this very cleverly. Instead of raiding people he raided but only aimed to get TC instead of loot so that he could place down walls which he destroyed so that he could go back and access the base any time secretly to get loot. Is there any way around this? Currently the remove tool works by being able to removing entities that YOU placed. Regardles of TC auth...

Using remover tool in raiding has always been an issue with this plugin. 

I'm not familiar with every single plugin on uMod and if somone is knows of one, feel free to point it out.

The first thing I would suggest is NoEscape, however that won't eliminate the issue entirely and would potentially represent a pretty drastic change to how raiding works, so you may not want that.

Alternatively, some technical notes that the developer of this plugin could implement in this plugin or another developer could implement in a separate plugin (using CanRemove).

• Check the ownership of surrounding entities, and only allow players to use the remover tool if:
  
  1. They own or are clan-mates/friends with the owner of a certain percentage of the surrounding entities
  2. There are no surrounding entities
• Periodically iterate over every entity in a base, determining who the majority owner is (or maybe just who the TC owner is) and change the ownership of all entities in that scope to them

Either one, or both, would mostly solve the problem of remover tool being used in raiding.  Both of the above approaches have their pros and cons.

  "Remove - Normal - Use Entity Owners": true,
  "Remove - Normal - Use Tool Cupboards (strongly unrecommended)": true,

This combines both checks

Ah I see so if they don't have TC auth and placed wall they shouldn't be able to remove it? I didn't want to set that to true in case someone raided, got TC auth and then they could just wipe a whole base...

Correct, it's a two way protection/check.

I love you
