I spectated you for several maps, I also warned you to get a weapon, also logs:
 21:08:32 - *DEAD* [jahboh] this guy is leeching for 3 maps now 
 21:08:37 - *DEAD* [Kapikulu_Mustafa] uhlrik leeches all the time 
 21:08:38 - *DEAD* [My_horses_name_is_Rebecca] yeap 
 21:08:42 - *DEAD* [The__Gunman] yes 
 21:08:45 - *DEAD* [Kapikulu_Mustafa] its like 4 or 5th time 
 21:08:48 - *DEAD* [My_horses_name_is_Rebecca] behind trees and such 
 21:08:52 - *DEAD* [Kapikulu_Mustafa] today  
This is what was said in chat after I warned you, I was also dead at the time.
And retirement is no excuse, always have a weapon, especially if the admin has already warned you to get a weapon!
Also, understanding what you did wrong and apologising for it is an important part of getting unbanned.
