Well i guess you are all right, and wrong
My idea is very very much simpler, it is so simple, that i honestly can almost not believe that it would actually work like the way i think it would.
But at least i have to try it out else we will never know.
I see that things with scammers are getting very complicated the more we use technologie in order to protect us against them. So i was trying to think the exactly other way.
Most scammers have (not all but most of them) to get in touch with you somehow. If they cant get in touch with you they cannot scam you.
So i think we dont have to protect ourself from scammers being there we just have to make sure, that they wont be able to contact you anymore.
So i wont code a thing. I dont even know how to code something, im not a DAO and there is no big technerd team, becouse thats where i see the weakness. The more technology we use, there more we get scammed...
So i wont do anything new, i will take whats already there in order to just do a single thing: Silence them. preventing them from contacting anyone. If they cannot get in touch with you over my marketplace no matter where ore what it is, they will leave all by themselves...at least thats the approach i will follow maybe i can present something for a first rudimental tryout in the next 2-3 weeks, but the whole things needs to be included into my main project which is my NFT collection. perfectly for doing first experiments
