It's really simple. Either you know its not encrypted or you don't. Don't make claims you can't verify. OP doesn't know that. You can assume, you can have an opinion, you can say whatever you want - none of it has weight or even meaning until you have something to show for it.
Your points on security are entirely true. The default should be distrust. That does not invite a witch hunt on every site you've never heard of making a claim. Had OP stated some key understanding they have and disclosed, then I wouldn't even be commenting here. I would have scrolled right past and never thought about it again.
How kind of you to bring some of their arrogant, universal pedantry with you.
Where are the pedantics? Lol I'm getting shit on for being reasonable and pointing to the facts that no one in here knows and somehow that's arrogant and pedantic. No sir, that's exposing people for spreading incompetence and hysteria.
You don't know the condition of that data or that backend. There is no pedantics there. A claim was made that can not be verified. There's no pedantry there unless you're upset that I want proof of claims rather than instant judgement. To be fair, I want proof of claims from that site before I would trust it either but I'm not gonna throw it into the pit just because it made a claim.
Or are you fine with people running around saying shit and spreading unverified claims they don't know or understand?
