A private military propped up over years by putin and sent to Ukraine turns on him due to the miserable conditions they had to endure and the overall management of the war. Make no mistake, Wagner's boss is an ultra-nationalist / authoritarian like Putin, but for now they're fighting each other.
I think it's early to say it will fail. There's a chance that security forces, conscripts and even professional soldiers are fed up with the way the Ukraine war has been going and they'll side with Wagner or not oppose resistance.

It's usually no big deal to visit an "unsecure website" for informational purposes if you don't type in any sensitive info.
Generally speaking treat it like a postcard where everything you write could be read or altered by "mail employees" or other third parties.
Woah! That looks seriously delicious.
