Internet begging, cyber- begging, or Internet panhandling is the online version of traditional begging, asking strangers for money to meet immediate and other needs (money, food, and shelter). Internet begging has the clear advantage to street panhandling in that it can be practiced with relative anonymity, thereby eliminating or reducing the shame and disgrace apparent of begging in public.
A cause website is a term for a cyber begging site that presents a *personal appeal* for funds or help.
