Sorry, for the late response but he's already been punished the day you reported him.
Please be patient with your appeal staff have to review it.
Is their a reason it's suspended? You're PlayerServer wouldn't be suspended without a reason I would probably get in contact with Staff Members and ask for the reason of your PlayerServer Suspension.
Posting your ban on here isn't recommended if you want to appeal you can appeal at
I'm gonna give you something that might help ( I say might because it might not work ) you can check the Timing Reports to see what's making the Server Lag. You can access the Timing Reports by executing the command "/timings on" and then "/timings paste" then look for the High Values on the page. What also may help is turning your Render Distance down ( In Minecraft Client-side) as a high Render Distance can cause Server lags/crashes I hope this helped you with what you needed. =)
