Charities are often have flawed aims, are mismanaged, or are outright corrupt. You are just as likely handing it to a swindler as you are a sincere charity. As scammers work full time on their scam it is more likely that legitimate charities are staffed primarily by volunteers, they have jobs and work outside of charity work. The best way to avoid scams is to find ways to give money to trusted individuals who are highly likely to contribute to the charity with little risk of embezzlement. You can do so by participating in the economy and purchasing independently developed games as their creators are far more transparent on social media for you to judge their character.
