Very disturbing, HADAX,Huobi and Coinbase don't accept watermarked copies of ID's and do not accept crossed out sensitive data (e.g. Dutch BSN number). Their support agents don't answer why they don't accept this and why they need specific data.
Fortunately HADAX eventually accepted a copy of the front of my drivers license (BSN number is on the back) but I guess a lot of clients uploaded their iD's without watermark.
We as a community should not accept exposure to Identity Theft as these companies (and many more exchanges, projects/iCO's, brokers, wallets) do.
