Hey I'm the staff member who banned you I had watched you basically log off while in no clip and then a ticket was made I took that ticket and investigated when I looked into your logs initially I saw that you had disconnected your self, however now looking into your logs and seeing that you were connecting and disconnecting and did look to be having connection issues just a little before your story does appear to be checking out.
The following screenshot is the one that initially made it seem to me like you LTAP'ed
But looking now at the rest of your logs you did appear to have connection problems
Next time just try to let us know but given you did get a black screen which i have gotten before, it would seem that this was just bad luck and situation.
