My mother was left an amount of money from my aunt,and after tv appeals she gave to a well known charity. She would then receive further thank you letters and how much more she could do if she gave x amount more. It is a fact that if you give to charities and they have your details,they will pursue you for more! You will also be on a list of " financial" doners and will receive requests from all sources. Best to donate to a real charity in cash only to be honest. I buy clothes etc in proper charity shops. The helpful work is being done, but I am not personally being hounded to give more.
