>>287899VPN: cost you money and you need to find a safe provider in other country.
Private Tracker: difficult to have access, but good privacy.
i2p: extreme privacy, extremely slow too. Ii is also extremely unpopular to use this darknet to download things because you will slow down the speed for everybody.
IRC: just go to to popular networks and share, share, share..
Also, you better be using Linux OP.
