Reduce Risk To Your Adventurers
Do not buy keys from a third party
Do not buy 16 digit keys - they are or will be useless
Do not re-use keys already purchased from a third party
Do not use proxy networks
Do not use web hosts
Do not share Keys or use Keys that have been made publicly available
Do not share accounts: possible reprisals for violations will envelop both party's shared accounts
Do not buy accounts or leveling services: such accounts are at high risk of being closed without warning
Also, keep in mind that anyone behind your network, or if your ISP shares your IP address (as in more than one persons are given the same IP address), gets restricted from battle.net, you will suffer the penalties along with them.
This is the unfortunate disadvantage of using a shared IP address.
Also, keep track of siblings and other people with access to your computer and/or network who play on Battle.net, as they can get you restricted as well
What’s new? Lol
Same old common sense warnings
Normally, I'd agree, but Blizzard is currently heavily enforcing all of those rules with extreme prejudice.
