Tumblr anyone?

Been doing OF since last October, almost all my subs have come from FB since day 1. Started a goth group which took off to 80k members, got a ton of deadbeat scumbags from that, what a shitshow. Was up to 500 subs at one point, then got restricted by FB and slowly went to like 75, then got myself back up to like 350, but since the start of summer it's been very slow, I'm down to like 225, and the page is dead save for a few good subs.

I need to get something new going and thought about trying Tumblr. Could anyone give me a rundown of how it is for creators, like what we can post, how to promote my OF page, all that sort of thing? Thank you for any help you can give me, I'm getting very discouraged.
