This is one of the reasons why I highly dislike leaving coins on exchanges and similar platforms. Paxful (a site where you can buy and sell bitcoin) recently added some stupid verification process to continue trading. If you don't do it, you can't buy and sell.

Bittrex did it to me before - and I didn't have a drivers license. So I had to travel to my moms house, get my birth certificate and passport and filed my drivers license as lost. Took about 2 weeks to fix that shit ... I couldn't withdraw my coins when that happened

So annoying

Which websites have hit you with that kind of thing - where they require I.D?
