There is definite survivorship bias; I suspect it's so strong that virtually all "do-gooding" you see on social media is for gaining status. It makes me extremely cynical of charities; perhaps just trying to do good "in the small" for the people around you is the best that one can do.
The corollary to your observation is that the do-gooding you don't see on social media is likely not for gaining status. Does that also make you extremely cynical of charities?
