The post-limit is the worst possible thing that could ever happen to the common Tumblr addict. After a user posts what Tumblr finds as "too much" pictures, videos, music, etc. they will reach their Post-Limit. At first, users will usually think, "What?" and after recovering from Post-Limit Shock, they will most likely be angry. A way to bypass this is, have the user go to their settings, and change their timezone to somewhere that is one day ahead of them.
You can no longer post on Tumblr for the rest of the day/night and you have to wait till 12:00 to start posting again.
