block list examples

Current real world block-list examples. Part of the effort to enable greater social-network-portability.


The following applications/services have a block or ignore feature.


Adium is a client side open source instant messaging (IM) application for MacOSX.

In the "Contact" menu, there is a "Block..." menu item that is enabled whenever a contact is selected or a chat window is frontmost. Selecting it brings up a confirmation box asking: "Are you sure you want to block USERNAME?" with buttons (Cancel) and ((Block)) where "USERNAME" is the IM address being blocked.

When blocked, in either (both if applicable) the "Contact List" window and/or in the chat window, the status indicator next to the USERNAME turns into a grey disc/oval/talkballoon with a red "x" set just inside its edge.

When such a contact/chat window is selected, the abovementioned menu item changes to "Unblock..." and when selected brings up a confirmation box asking: "Are you sure you want to unblock USERNAME?" with buttons (Cancel) and ((Unblock)).


Dodgeball is a social network location presence service.

On your my profile page (logged in version), on the right hand column there is a section with the heading and message:

friends you are NOT sending messages to

These people will not receive messages from you when you check-in. To add or remove people from this list, click manage friends.

Below the message it lists the people that are in your dodgeball "block list" though they never call it that.

The text "manage friends" is a link to your manage friends page (logged in version) which lists more explanatory / descriptive text, followed by two equal width columns of friend icons. The left column with heading send & receive messages from these people has icons of those that you are NOT blocking, and the right column with heading don't send or receive messages from these people has icons of those that you are blocking. Clicking on an icon in either column moves the icon to the other column.

Only once in the descriptive text is the word "block" used, in this sentence:

Regardless of whether you choose to send to these people or block them, you will still appear as their friend on their profile page.

There is a separate option mentioned in the text to "delete" a friend, where it states:

If you want to delete friends for good, click here. Just remember that if you delete someone, (a) you can't "un-do" it and (b) they can see that you've deleted them.

Dodgeball's block list is quite different from the others here in that it is for only blocking people that you have explicitly added to your friends list on Dodgeball, whereas all other blocking examples are for blocking arbitrary people on the system.


Flickr photo hosting community.

"block this user" link when viewing a user's profile.


MySpace social networking site.

block_1.gif (Block User) link when viewing a user's profile.


Twitter simple updates community.

"block ((username))" link when viewing a user's profile, just under their friends list.
