Mudfish vpn support

Hello Blizzard support. My ISP has poor routing to your servers. When i use Mudfish. My ping is around 20ms lower on average. However, i’m concerned about using it.

My sms protect informed me my account was locked, however I was able to easily able to unlock it.

I’m assuming my account was locked due to me suddenly playing from an IP that i’ve never been at, however I just wanted to get an official stance on whether or not i can use it.
