are you now receiving some emails that you have never received before? That's probably they've sold not only your identity but also contact details.
Yes, I have received several emails and sms some time ago, I previous joined BCNEX campaign and I did KYC there to get payment, so I immediately remembered that sms and email I received came from the data they had sold
Well, that's what really usually happening and I've seen people that have shared the same experience as you. They've taken your information and now there's another company or project that's doing their advertisement and you're now part of their database.
That's annoying.
