I have found a way so Bl or Lc wont recognise you use namespoofer:
1)Open Namespoofer
2)Open
Wc3
3)Enter B-net and then go to the custom games
4)Go to the Namespoofer and add the name you want to have
5)Press Change Name
And now there is the exploit:
6)Close Namespoofer
Now you will realize that you will have the name that you entered at Namespoofer without having Namespoofer opened in your pc.
ex.I enter game with the name: Arthas.Usually someone in this game has bl or lc and says"WARNING!Arthas is using Namespoofer" and then they kick me.But when I close namespoofer i enter a game again which has bl or lc in it and they don't realize that the name i have is from namespoofer
