services – How do I stop privoxy on mac?

I’m on macOS 10.13.6

I’ve no idea when and why the privoxy service is installed.

$ lsof -i :1087
COMMAND  PID    USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
privoxy 1876 ubuntu    3u  IPv4 0x48418fcf2ac40703      0t0  TCP localhost:cplscrambler-in (LISTEN)

I tried kill the PID

$ kill 1876
$ lsof -i :1087
COMMAND  PID    USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
privoxy 5676 ubuntu    3u  IPv4 0x48418fcf23431063      0t0  TCP localhost:cplscrambler-in (LISTEN)

but it started another immediately

How do I stop this privoxy service on mac?
