I have nearly 20 separate Tumblr accounts right now. I've been growing my follower list on some of them for almost half a year now. I'm wondering if there's a limit to how many Tumblr accounts you can own? I don't use proxies, all of my blogs are SFW, and I don't post spam. Can I just keep making blogs like this? I'm worried eventually some might get deleted and my IP banned. I'm also wondering if it's safe to post AdSense ads on all of them? Oh also, I made a script that makes all of my blogs automatically follow ~100 blogs/day throughout the day, if that affects anything..
