I think most civilians in Gaza are busy trying to survive. People are starving and trying to avoid being killed. Constantly moving. Even if starving refugees did run in to one of the hostages, how and to who would they relay this information? And with that information relayed, what could the informant expect happen to the the camp that they stay in?
A lot of people don’t seem to mind it, but to me it really tastes terrible. Even if I got it for free I wouldn’t drink it.
