Embattled social media platform 
Parler is offline after Apple, Google and Amazon 
pulled the plug on the site after the violent riot at the U.S. Capitol last week that left five people dead.
But while the site is gone (for now), millions of posts published to the site since the riot are not.
A lone hacker scraped millions of posts, videos and photos published to the site after the riot but before the site 
went offline on Monday,  preserving a huge trove of potential evidence for law enforcement  investigating the attempted insurrection by many who allegedly 
used the platform to plan and coordinate the breach of the Capitol.
The hacker and internet archivist, who goes by the online handle 
@donk_enby, scraped the social network and uploaded 
copies to the Internet Archive, which hosts old and historical versions of web pages.
In a tweet, 
@donk_enby said she scraped data from Parler that included deleted and private posts, and the videos contained “all associated metadata.”
Metadata is information about a file — such as when it was made and  on what device. This information is usually embedded in the file itself.  The scraped videos from 
Parler   appear to also include the precise location data of where the videos  were taken. That metadata could be a gold mine of evidence for  authorities investigating the Capitol riot, which may tie some rioters  to their Parler accounts or help police unmask rioters based on their  location data.
Most web services remove metadata 
when you upload your photos and videos, but Parler apparently didn’t.
Parler quickly became the social network of choice 
after President Trump was deplatformed  from Twitter and Facebook for inciting the riot on January 6. But the  tech giants said Parler violated their rules by not having a content  moderation policy — which is what drew many users to the site.
Many of the posts made calls to “burn down [Washington] D.C.,” while others called for violence 
and the execution of Vice President Mike Pence.
Already  several rioters have been arrested and charged with breaking into the  Capitol building. Many of the rioters weren’t wearing masks (the  pandemic notwithstanding), making it 
easier for them to be identified. But thanks to Parler’s own security blunder, many more could soon face an unwelcome knock at the door.
