I don't see the point of props, anyway. I don't think I'd care if they weren't free. Besides, what do wewe even mean kwa free? They aren't "free" now, because someone else still has to actually give them to you.
heshima will never have to cost money. It could result in violence, and in extreme cases, even lawsuits. Not a good idea to bring money into something like this. Plus, richer people, au people willing to spend zaidi money might feel that they shouldn't be giving heshima to people who won't give back, i.e. people with little au no props, thus creating social classes on Fanpop, which is one of the things many people jiunge fanpop to temporarily escape from. I know that if wewe heshima started costing money, I would protest against it, and if that didn't work, I would quit.
