A Moderator / A Malware expert - gave you a "Real Response" ....no nonsense there !
Even if your Neighbour approves this use of sharing his Wifi as said it would probably be against the Contracted Isp Service.
And also if and any illegal downloading on your behalf would then be his fault as the Service Owner.
If you need to do something behind Closed Doors ....thats your option.
But you cant ask an Establishment or Others how to do it , without them then being Accountable to the Fact.
If you need real responses then a General Google will give you the Answer , and that wont implicate other parties trying to assist you.
Most times people dont like an honest answer to a question when provided.......Thats Life.
