Seeing how tumblr loves to ban nsfw blogs just out of the blue I'm wondering why not just make new blogs every month? Most proxy sellers allow you to change proxies every month so why not make new blogs, do all your following, liking, and posting for a month. Then load up the queue, delete the blogs out of your bot, change proxies, and make a new set of blogs. Or maybe just keep the most popular ones after the month and dump the rest? I just don't get the whole "build one quality blog" crap when you could work on it for 6months only to have it banned and have to start again from scratch.
