Twitter has announced their ability and intention to block selected content by country.
We haven’t yet used this ability, but if and when we are required to withhold a Tweet in a specific country, we will attempt to let the user know, and we will clearly mark when the content has been withheld. As part of that transparency, we’ve expanded our partnership with Chilling Effects to share this new page, which makes it easier to find notices related to Twitter. There’s more information in the Help pages, both on the Policy and about Your Account Settings.

In the past, they would take all the positions of your rankings and average them together, now they are taking only the top positions.” —
