Parsing the data dump from Parler will take some time.

But just to give you an idea of its use.

This is a global shot of videos uploaded over a defined time period.

Fair to say Parler was mostly US users.

From this data set, UK (England?) was the second biggest user set

The data set lets you drill down a fair bit. Each of those dots on the map is a geo-located video upload.
During the upload Parler -unlike say Twitter - retained location metadata. Sloppy operation.
Privacy probably not a big concern if your profiting off hate merchants...

As the US impeaches its President for a second time and the FBI has issued warnings about potentially armed paramilitaries at each of all 50 capitol buildings over the next few weeks, its probably a good a time as any for anti-fascists (thats most of us yeah) to get this data

As we can see use in the UK is predominantly England, which is no surprise English nationalism and white supremacism are a skip and a jump apart.

Again this is just a quick glance.

We can go further into the data

We can pull into specific points. This is a cluster in Ireland and for each recorded upload there is an associated longitude and latitude, the time and date of upload and a unique assigned video ID.

Other iterations of this map include direct links to video content.

Much of this is the initial work of a massive data set, with the focus currently on video. More will come out over time.
