So I haven't been trading for about two years now. I remembered that I had a poloniex account that I used to trade some Bitcoin for monero and I wanted to see how much Monero I had purchased as I got a new computer and haven't reinstalled my monero wallet (I have the seed for it).
Anyway, when I logged back into poloniex, I went through the normal log in process and had a code emailed to me. Then, after I successfully typed in the code, I was transferred to a page where they request I update my profile information. It asks for normal information like street address but also my social security number. In a banner at the top of the screen, it says I will also need to provide a scanned copy of a government issued photo ID.
Is this a normal procedure at poloniex now? If so, is Poloniex capable of safely storing this sensitive information?
