Someone is trying to hack my Mustang6G account?

I just got this notice from the automated server:

Dear Darkslide,

Someone has tried to log into your account on 2015+ S550 Mustang Forum (GT, GT350, GT500, I4, V6) - Mustang6G.com with an incorrect password at least 5 times. This person has been prevented from attempting to login to your account for the next 15 minutes.

The person trying to log into your account had the following IP address: 101.4.136.66

This IP address is in China! Why would someone try to hack my Mustang6G account!??

Someone tried to hack my account too, back traced the ip address and it also came from China. Maybe they are trying to hack our accounts to gain access to our emails and from there they can do some damage considering people get bank statements and other crap through their emails. I changed my passwords twice since yesterday.
