Charge up-front? (Patreon)

Hey there everyone! I wanted to inform you that I'm seriously considering switching the pledges to be charged up-front. This means that any Patrons will be charged at the beggining of every month, rather than at the end of it. Also, any new Patrons will be charged immediately when they pledge. I'm considering this option because of just so many people pledging for a few days, downloading all of the exclusive stuff and then canceling their pledge, not paying at all. That's not fair at all. I will probably enable this option for the next month. I'd like to hear your opinion on this matter :)
