Changing Tiers Policy (Patreon)

Hi, I just wanted to make a quick post. Recently it's come to my attention that people are quickly changing their pledge amount from $7->$2 or $1 to get rewards and then not get charged. I don't currently have the ability to charge up front to prevent this. 

I'm asking anyone who is doing this to please refrain from doing so. If I see you doing this I will possibly block you. I don't think it's cool to be cheating the system. I know people some people don't have much money to offer, and that's fine, but I'd rather you not pledge at all instead of cheating the system like that.
