Anyone giving up their KYC for some token without knowing the possible implications is probably ignorant of it. They don’t really understand what it could mean, and in most cases, it ends up with them becoming a victim of laundering or shady dealings then they wonder how it all happened in the first place. As for those who know exactly what they’re doing and understand the implications, they deserve whatever comes their way.
The tricky part is telling which is which…
They don't know the effect that they can get. Becoming a victim of laundering is a simple thing that may happen if they give to the wrong person. Their KYC can be used to verify many things especially the platform doesn't need online verifications so those who use it will benefit from the KYC. The thing that they can do is just not give their identities to any unknown platforms and always research before they want to do verification. That will help them to stay away from the bad things that can occur.
