On Monday, as the Facebook posts spread on social media, questions were also raised about Ms. Jones’s motivations in sharing Keaton’s story, but with little solid evidence.

The mixed martial arts fighter Joe Schilling shared a screen shot of an exchange with an Instagram user named kimberlyjones_38 in which the user made a racist remark, but there was no indication that the account actually belonged to Ms. Jones.

By Monday afternoon, both the Instagram account and a GoFundMe campaign that it had linked to had been deleted. A GoFundMe spokesman, Bobby Whithorne, said the campaign had been removed before any money was collected because “the identity of the campaign organizer did not match anyone associated with the family.”

Another GoFundMe campaign, started by a person named Joseph Lam, raised more than $58,000 in two days, but Mr. Lam acknowledged that he had no connection to the family; he wrote in the campaign’s description that he simply “came across” Ms. Jones’s video on Facebook and “felt compelled to help.” On Monday, he suspended the campaign.

Asked whether GoFundMe had verified that the funds already collected would go to Keaton, Mr. Whithorne said the company was working with Mr. Lam to ensure that.

“When a stranger starts a campaign and does not have a direct connection to the individual they’re raising money for, funds are collected by our payment processors, held, and then only released only to the person named as the beneficiary,” he wrote in an email. “All funds are on hold until we’ve received additional information from the beneficiary of the campaign.”
