Dear blizzard we have tried to reach about this situation via tickets several times.
We have sent everything u needed to take an action, screenshots and all.
Because of your current report system some players heavily effected including crafters in trade chat with many other.
There has been reporting exploit going on almost for 2 weeks now. There is two boosting communities taking over Trade/Services chat by themselves and not allowing anyone else to do anything.
When you post something even if its on Trade chat and not services u get silenced in 5 minutes. They are mass reporting people to make more profit for themselves. These people using your player GUID to report you via addon/script/bot. Even if you are offline they are able to report you because of GUID. They are also tracking the people they are silencing and reporting them before their silences appealed.
I hope that you will see this post and take an action. I can share the boosting community names with their discord if its taken seriously from your side since u were only giving us Automated ticket answers.
