Users of the Parler social media platform who participated in the riots last week at the U.S. Capitol are reportedly uneasy following the announcement that several activist hackers archived posts as they were happening in real time during the riots, and that they will release the posts publicly to assist law enforcement with investigations. Another activist hacker is reported to have said that she archived material as it was being posted to show how the platform was used to plan the attack and for communication by participants during the assault.

Parler is reported to have been a popular mode of communication during the months leading up to the election last fall after Facebook and Twitter began reviewing and labeling content that was false or misleading.

One of the activist hackers alleges that she archived 30 terabytes (equal to 30,000 gigabytes) of publicly-available posts of the events leading up to and during the riots so they would be preserved before the platform was taken down, which occurred on Monday.

Some of the data that were archived includes legally-obtained GPS data while posts were made by those participating in the riot. The GPS data show that Parler users were posting videos and pictures while they were inside the Capitol, including both chambers of Congress and offices of some politicians.
