Gonen32: I think I'l just drop it. Their TOS are very unclear and I don't want to attract more attention to myself with the risk that I accidently broke any of them (does sub and then unsub to Humble Monthly every now and then for a specific game counts ?)
amok: Actually, it is very clear: "except as otherwise specifically set forth in a licensor's end user license agreement, as otherwise agreed upon by a licensor in writing or as otherwise allowed under applicable law, distributing, transmitting, copying (other than re-installing software or files previously purchased by you through the Service on computers, mobile or tablet devices owned by you, or creating backup copies of such software or files for your own personal use) or otherwise exploiting the Products (defined below)
in any manner other than for your own private, non-commercial, personal use."
trading is not own private use, and it is commercial. So yes, it is very clear. Even the
FAQ:
"Can I sell or give away my keys?
Humble Bundle products are for personal use only. We do not allow selling or redistributing keys from your purchases. You can gift individual keys to friends using our gifting system, which you can read more about here.
You can also gift your friends whole bundles or Store items on our website by clicking the gift option at the end of your purchase.
Read the Humble Bundle Terms of Service"
is quite clear, so any trading is against the TOS and you are on your own for breaking it.
I keep posting that but you have more respect in here so we'll see if you have better luck.
