Your ban is justified. You left the server during an active roleplay situation while being demoted, then rejoined only 50 seconds later. This is a clear case of LTARP. Additionally, you have a recent prior LTARP offence just 8 days ago which is why the length of the ban was increased. Your explanation does not change the fact that you intentionally left the server to avoid roleplay consequences, and you could have handled this situation better by simply just communicating to staff, or those around you, that you were having "issues" with your internet connection, instead of just leaving the server.
This ban will remain in place.
