Recently built 2 niche sites and I am looking into using Pinterest majorly for one of them. However, I want to find some way to automate the process as I may need to be running several Pinterest accounts. I've seen the bots on this forum like healzer's PinBot and another called Pin Blaster, unfortunately none of these fit within my budget at this time. Does anyone know of a bot that follows/unfollows, likes, pins , creates boards? For free? Is there even such a thing?
