From the Writing a good bug report thread:
We read every single thread that is posted on this forum. However, we will not always respond to every thread. If you do not get a blue response, please DO NOT bump posts. We will ignore and possibly delete any post that simply says “Bump” or demands a response from a Blizzard poster.
This IS the correct forum to report game bugs. Or the PTR Bug Report Forum for current PTR game bugs.
