I just saw that Ledger started to open registration for new nono S plus device waiting list, but I would not suggest anyone to use their main email address or pre-order this device.
Do you think they will lose email address? We can do a little test: create a new mailing address and put it on their website. If phishing offers (or what threats do you expect?) come in, we will know who is to blame. But there is a nuance, it is not known how long this will happen.
I like this idea! Since I often use purpose-specific email addresses, I already noticed a few times that I get lots of spam on some and none on others, so it does really help identify where it comes from / who is leaking & selling email addresses. Would be interesting to check with Ledger.
