Gurbaksh Chahal, the Gravity4 CEO who is appealing a prison sentence stemming from a domestic battery case, recently wrote on Medium about how his charitable foundation is "transforming the lives of the less privileged children in India and several other countries."

Specifics were a bit fuzzy, and federal tax filings reveal that the nonprofit did not spend a single dollar on charitable activities (direct donations, indirect donations, grants, etc.) in 2013, 2014 or 2015. It also seems to have received no donations during those years, with a bank balance that usually sat at between around $400,000 and $500,000.

I used an email form on the nonprofit's website to ask if the Chahal Foundation made any charitable donations or related actions in 2016 (for which tax records are not yet publicly available). For example, Chahal posted a YouTube video suggesting a January 2016 trip to India that involved local schools. Rather than providing any actual information, however, Chahal simply insulted me via Twitter and Facebook, referring to yours truly as an "idiot," "POS blogger," "douchebag" and someone "looking for a fake story."

Yeah, he's a charmer. And, as of now, he's also someone unable or unwilling to back up his big philanthropic claims.
