Your right to block $$ clients
 
If you don't want to contribute any $$ to commercial clients, or clients that block XoloX without reason, or clients that have guntella domination in mind, apply the following patches so you don't connect or share files with them.
It's now your choice.

for the file "Upload.cpp" modify "Upload::initUpload()" and recompile, the mod is only a few lines
see "/////////// THIS IS THE MOD!!!!"

Code:
