There are two ways to this things.
There are people who record their moments of charity to inspire others about the need to gift people around. Some use those videos and their payouts to sponsor more reach outs and helping hands. I know of somebody who's doing that and very transparent with it although I don't trust him completely, he had shown some good evidence of the work he's doing, I'm talking about (VDM).
Then we have some people who's ambitious motive of recording is to make caricature of people they've helped which is sad.
I think it all goes down to their motives and a smooth agreement with the people they're recording. If they don't find it disturbing they can go ahead to post the video, it's simple...
