I think its just true...
For example this code is protected:
A7 60 04 00 00
01 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00
And this is an unprotected code:
A7 94 3A A7 02
A0 86 01 00 01 00 00 00 00 00 00 00 00 00 00 00
So you see the difference. The 6th and 7th numbers...
I hope everyone knows now whether a server is protected or not (interlude)!

I proved it on some servers and the video show me the same result! So look here is an other Video about an unprotected server:
Ich hasse es so ne scheiße auf englisch zu schreiben!
