i just found out about it but apparently this has been the plan for some time now. it seems like it was first for publishers to gather BAT tokens and now it is to be enforcd for anybody who wants to use the wallet (Brave Rewards).

it is worth noting that KYC is not requires if you use it as a browser but the question rises, why would you want to use it after this and when there are good browsers like Firefox available which is the original code of this project?
i had uninstal my Brave Browser since they asking me doing KYC when using Uphold wallet. i had nothing to hide and honestly KYC needed to prevent someone from committing a crime , but bad news is when your Data being Sold? that's not a wise option.
