Tumblr tries to "look good" but has the worst treatment of customers. They trap you with campaigns you need to pay to get more "likes" for your works. But you won't get many. They send you messages that you campaign was "full impact" with many views and hood-lookung statistics. But you don't have the "likes". You try to contact them -which is really difficult - but you won't get any (senseful) response. Tumblr is just blablabla... won't recommend it for any artist!
