1. Safe.
Last ban wave is due to valve introduced a honey pot that fishing hacks to access some data that is not accessible via normal way.
The honey pot is removed after the ban wave.
Right now whenever changes is introduced in update, the staffs are monitoring the code changes if it is dangerous.
If there are dangerous changes I think we will get notified.
2. All functions still works except Visible by enemy feature(half broken)
Visible by enemy feature is patched by valve though we found a way that only works half of the previous VBE.
Right now it only detects when you enter enemy vision, but it will not detect if you quit from enemy vision.
