Isn't there a possibility to make a call from a public phone or similar? How much does a temporary "burner phone" cost, I am willing to donate the cost.
The town I live in doesn't have any operational public phone boxes anymore as far as my search revealed. Mobile phones killed them all unfortunately.
Prepaid burner phones or prepaid SIM cards aren't avalaible officially without KYC unless I go for the black market or other shady offers. That's not quite my cup of tea, sorry.
Thanks for the offer to donate, but I doubt it's worth it, see below.
I am very interested in what 1api.net has to say about all the reports so far and why they do not respond to them.
To some extend, me too. But as Haunebu says, it may not yield anything. They could simply refuse to comment or say anything. It's already not promising that they seem not to respond to any report sent to them. They sit it out and get away with it if no German authorities (cybercrime units?) have a reason to pressure them or ICANN kicking their butt (if ICANN actually does this, waiting to see proof).
I can't really contact German cybercrime without revealing my identity and without personally being scammed I doubt they would persue any hints from me even with good details on examplens' fraud expose website (kudos!).
Call me a chicken, I won't be offended. I value my privacy in crypto space.
