well, OP is anon so he/she could have many reasons to share it here
from building reputation to making connections... maybe?
here is a good place to find like-minded people in terms of gambling.
I wonder if you are able to win hundreds of thousands of dollars, then why do you need a reputation anywhere and any connections? Why do you even need publicity? If I was capable of making that kind of money betting I wouldn't brag about it either in real life or on the forum, I can't think of any reason why I would want to do it.
I wouldn't either
but remember that people have different aspirations, just because we would chose not to do something it doesn't mean that other people would do the same choice.
the best way to learn more about @NAPK1NS_RA3 reasons is... to ask!
