Turn and burn every month?

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.

I run 7 'quality' blogs and only have to mention my new blog to get it over 10k followers within a day or two. Also, the NSFW niche is a horrible niche that is saturated. Followback rates are low; don't waste your time.

Furthermore, I read many times that Tumblr is a 'porn' website because there is a large amount of porn on it. So many people are advised to pick that niche and think that 50% of Tumbr is into that. Truth is, there is only lots of porn on Tumblr because people go where that thing between the legs is taking them and post a very large amount of porn content. You can't even call porn a niche anymore, it is not specific enough. Porn is probably 0.1% of Tumblr users, not content.

If you don't want to get banned then build a quality blog.
Leverage is key.

Build a quality blog like the above poster said. It's too much hassle and it won't bring you as much money as you would get if you put the work into a proper blog. With a decent blog you won't have to worry about being banned so you can increase the quality even more.

You have to hire a quality writer with it's professional services.
I hope you'll be relaxed with Tumblr by using professionally written blogs.
