Many people love to raid in Rust, but not many people enjoy getting raided. Sadly any base can and will get raided, no matter what you do to prevent it. Offline raiding is the preferred method of raiding and is hated by all except the people raiding your base.
As usual my base gets raided, but the guys that raided my base were hacking and got banned the next day... but that was not going to change the fact that my base had been destroyed.
In the image below you can see the highlighted wall. They raiders built a TC behind here, stopping me from rebuilding or picking up any of my stuff.
Sadly one can not pick up certain buildings which are really expensive, this one in the picture below takes forever to get and losing one can make you really tilted.
Once I had broken down that wall with the TC behind I was able to loot some of my stuff and create a new base which you can see in the below picture.
After a few days most of my previous base had decayed away.
