I thought he was stream sniping even though he wasn’t because it looked suspicious, but I looked, and no one was in my stream. This was my mistake, and I don’t want anyone to get suspended. Thank you for answering my question.,3
Fortnite (right?) drama. 
Consider asking about this in the Fortnite forums, this is not the place.
On the other hand, someone admitting to making a mistake on the internet is quite an uncommon sight.
Congrats, you’re an honest human being!
