I got stung after opening an MT.GOX account. I transferred £100 from my bank account to my MT.GOX account and bought BTC. When I tried to withdraw it it stated that I had to verify my account even though it was only a small amount and I had complied with all the requirements. I am very wary about uploading personal details over the internet...especially passports, driving licence etc. In fact I wasn't just wary I was furious...it's like blackmail...unless I give them certain details I can't access my funds. To say it is disingenuous is an understatement...how do I know my personal details are in safe hands? I don't!
