At the end of the livestream, the balance of the Syrian test account was $33. TikTok had taken 69% of the value of the gifts.
TikTok influencer and ex-professional rugby player Keith Mason donated £300 ($330) during one family's livestream and encouraged his nearly one million followers to do the same.
When told by the BBC that most of these funds were taken by the social media company, he said it was "ridiculous" and "unfair" to families in Syria.
"You've got to have some transparency. To me, that's very greedy. It's greed," he said.
The $33 remaining from the BBC's $106 gift was reduced by a further 10% when it was withdrawn from the local money transfer shop. TikTok middlemen would take 35% of the remainder, leaving a refugee family with just $19.
Hamid, one of the TikTok middlemen in the camps, told the BBC he had sold his livestock to pay for a mobile phone, SIM card and wi-fi connection to work with families on TikTok.
He now broadcasts with 12 different families, for several hours a day, according to BBC.
Hamid said he uses TikTok to help families make a living. He pays them most of the profits, minus his running costs, he said.
Like the other middlemen, Hamid said he was supported by "live agencies" in China, who work directly with TikTok.
"They help us if we have any problems with the app. They unlock blocked accounts. We give them the name of the page, the profile picture, and they open the account," Hamid said.
