Thank you for posting this! I have been complaining about (and downvoating threads) that POS site for days now, everytime they spam this site.

Never even heard of that site before today.

I couldn't tell based on one link only, but my overall expression is something like 30/70 or 20/80 for the amount of valuable content there. For example they were one of the few mentioning Child Trafficking markup in the White House last week. On the other hand their tagging is awful and they don't check at all what their writers share.

There are both worse and better sources, and while this source sometimes has something valuable, those are usually available already somewhere else. I've never seen an original, valuable post there, but if someone has - please link

To your 2nd question on Vault7, that content is by Victurus Libertas which value as a source you can easily estimate here https://www.youtube.com/channel/UCnFxU-3nW6XAAQfHkOFMalA/videos
