He indeed is low lvl. 
However there's been 2 bans for teamwounding in your past. 
I was not there this time, so it's quite hard to reenact the thing. 
But if i think about you being banned before for intentional teamwounding, Flurry providing lots of screenshots that also show you leeching and Wilburg supporting Flurrys request, i have to do something. 
You are banned for one day. And don't even try to argue. You're lucky it's just one day.

1st: don't leech. If you have to check the site, do it while you're dead. 
2nd: don't teamkill. If it happens accidentally, apologize! 
Thanks for reporting.
