Hello @Pranilsht, I hope you're doing well. I shall be answering your query.
Disconnects often occur, the spontaneous disconnect itself is seldom an issue. You won't be punished just for a disconnect, unless there was some other violation involved in it. You can refer to our PvP Rules and the Explanation of Illegitimate Rank Boosting to familiarize yourself with such violations, and avoid them. Thank you for taking the time to bring this up to us, caution is always a preferred choice. On a side note, please abstain from discussing or bringing up your previous punishment(s) here.
I hope this satisfies your concerns, if you have any further questions, please let me know.
