Share your block list with others
By exporting your block list, you can share the list with others so they can block the same list of accounts.
To export your block list:
Navigate to your blocked account settings on twitter.com.
At the top of your block list, click All to export your full block list. Click Imported to export the block list(s) you have imported.
Click the Advanced options drop-down menu.
Select Export your list.
Confirm the accounts you want to export.
Click Export and a .csv file will be downloaded to your computer and you can share the file with other Twitter users. If your block list exceeds 5,000 accounts, your list will be separated into multiple files.
