JPenno: Theft - the generic term for all crimes in which a person intentionally and fraudulently takes personal property of another without permission or consent and with the intent to convert it to the taker's use. In light of the above it is theft. You do not have their permission to use it. I would be more than happy to run this argument in court and be 99% certain of winning.
Kieran: I can't believe you couldn't see stealing next door bandwidth a theft! That's amazing!
It isn't theft, because it isn't "property". Bandwidth is an intangible. No 'property' is being taken.
Nor is it 'theft' if I'm not aware that it's illegal. I press four buttons on my Japanese laptop and I have the use of a local network. Whose network it is, I don't know, and since I don't use their bandwidth at the times they bother to make use of it up to now, no harm at all was being done, in the slightest.
Jason has kindly pointed me to an item suggesting using a LAN to access someone's internet service without permission may amount to a computer offence, so I won't. But wannabe-lawyers giving me supposedly expert law lectures on what is or isn't theft isn't appreciated. Qualify as lawyers first if you want to tell me what the law is, please.
Jason, there is no such thing as "tantamount to theft". You've said tapping in to someone's unused bandwidth at times when they are making precious little use of it is "stealing" - so you prove that, please, or withdraw your allegation.
I'm not a thief. I don't think I am doing anything wrong by it. If you can prove to me that it is a wrong in law, go ahead. If you can prove it is classified as a criminal wrong, I won't do it. Otherwise, apologise please.
