Thanks for the link abyssin, indeed seems very interesting.
Btw, I tried accessing my profile from Wayback Machine and got a nice "This URL has been excluded from the Wayback Machine". Really Couchsurfing?
Also, I forgot to mention that the message you get when you login to couchsurfing.com is a landing page that says: "Due to the impact of Covid-19, we need your immediate help to keep Couchsurfing alive" and then the only options you have are: 1. Pay with Credit Card 2. Pay with PayPal 3. Logout (https://imgur.com/g7QKHEt)
Their site totally looks like ransomware.
