I'm sorry that you've had such an unpleasant experience.
You really don't need to worry about being reported. In the days of the old Supercell Forum I experimented with reporting to see what happened.
A lot of time has passed since then and, unfortunately, I don't have the details. I can't see that the information made its way onto the JHD Legacy Board either.
My recollection is:
For anything to happen a player needs to be reported by several
different hoodies;
If sufficient hoodies report the same player within a given time the player concerned is silenced in chat for 24 hours;
The player can still see the chat during that period, but cannot participate;
After 24 hours have passed everything reverts to normal.
Most importantly, Supercell is not involved.
My guess is that there's an algorithm that reacts to players being reported.
Please be aware that my recollection may be a little foggy at this late stage, but I'm certain that the gist is correct.
I hope this helps.
