Heya!
Glad to see your reply!
I do understand how you are feeling in this situation as your account is temporary suspended and you don't understand how you can get the hwid ban. However, it is possible that someone in your family or friends used third party tools from your device.
Also, please know that the correctly placed penalties cannot be removed or modified. Lifting or modifying penalties like these would mean we accept and promote cheating. Keeping the structure means protecting competitive integrity and peace within the community.
We're not banning the specific player from ever playing the game again, but only the account where offensive behavior was observed. I hope this makes sense.
Since we've already given you all the available information on the topic, we will have to close the ticket.
If you have any questions, on different topics, please create a new ticket.
