StackGambler is very shady, I am very suspicious of him, but I am not sure who he is.
One of the photos seems to imply he had the server seed of
CrashDoge when he turned 5,000 doge into 6mm doge.
The owner of the website had asked StackGambler to provide his ID, and both this and the reason why providing ID was refused was probably because there was cheating on the part of StackGambler.
edit: corrected win to reflect 6mm doge, not 4mm
