Tumblr is known for being racist, extremely rude, and not very skillful in their job. They can fix small technical bugs, but as far as matters that really effect the users they ignore. They let harassment happen, suspend accounts without fully researching claims, or even a warning. This has got to stop.
8/15/2012 - I've recently as well as others, had my original artwork taken down at the will of another UNLAWFULLY. For months this has been happening and Tumblr has not done anything. They have not researched claims to find they are truly false, they mindlessly go with whatever someone says. I've had simple text posts taken down. This is violation of my right of free speech, the first amendment.
