There are a lot of people with serious problems and basical hardships that they have no one to look after them. So it’s very important the work that some groups and associations do to help these people. But, unfortunately, only the goodwill would be insufficient without financial contributions. That’s the reason to look for original ways to obtain money.
So, in this situation on the world, if you ask about it’s or no a good idea to sponsor some activity for charity, I have to answer I’m in favour to do any proposal in this way.
