People got percentages back for investing in Birth of a Nation. You get a poster for donating to this.
The key word is
INVESTING lol. Tariq ask for
DONATIONS lol. Motherfukkers do not even know the difference between investing and donating

.
Obviously they received a percentage back from
investing into a movie that cost 3.5 million to make

. You would be an idiot to
invest $500,000 into a 3.5 million dollar movie, that generated 16.5 million; and ask for your same $500,000 back


. That's common investment, compound interest and business skills.
Tariq ask for
donations, you are not required by law to give back donations

, unless you do not produce a product, in which you were asking for donation to fund your product.
That happen to Tommy Sotomayor and his "movie" A Father Less America," he was sued and had to give back
donations, because he did not produce a product in a timely manner and he misused the funding

.
Tariq on the other hand, got the ball rolling with his own money and showed pictures and previews of the movie to come and asked for donations of any ammout. To reach his goal of $200,000 in a timely fashion, he said if you donate X amout you will recieve a dvd, t-shirt, poster, or your name will be in the producer portion of the movie.
Giving items for donations are not required, but if you are
INVESTING, yes you have to give back the money that was invested to produce your product.
