GoFundMe, the “do-it-yourself” fundraising website, announced it’s helped campaigns raise more than $3 billion since it started in 2010, with a majority of those funds amassed in the past two years. For example, $11.2 million was raised through the site after the 2016 flooding in Louisiana and $9 million after the nightclub shooting in Orlando, Fla. On the one hand, it’s possible that these campaigns are eating into donations that would otherwise go to more traditional nonprofits. On the other, nonprofits might be able to make better use of the platform, although they’d have to share about 8% of every donation with GoFundMe.
