I now installed a cheat protection software. The important part is that it does not allow you anymore to lag-climb out of holes by quickly placing blocks below you in restricted areas (spawn, other people’s lots etc).
This means that there is a risk for you to get stuck. While in the normal world you can get out of a hole by using /spawn, in the darklands spawn area that is not possible. You would have to wait until I come online and get you out of there. So watch where you walk!
If you get stuck, you can leave a message anywhere on the site with your coordinates (press F3) and I will fix the area so you can get out when you log back in.
