Hello again,
Unfortunately, for some restriction, it doesn’t have to be you doing something wrong as you can read here
“If you are absolutely certain you did not spam, 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 2, you will suffer the penalties along with them.
This is the unfortunate disadvantage of using a shared IP address.”
Please read through that whole paragraph as it might explain it for you.
Kind regards
Kiemmaki
What’s your opinion?
