I registered to Pokerstrategy like 4-5 days ago and I finished the quiz,filled out the details and also sent the picture of my passport,now I received a letter which said:

Unfortunately, we are unable to process your security check as the
information you provided is insufficient.

Please send us your photos again and be advised that you can only blank
out your signature.

All my information was clearly shown in the picture of my passport and I can't understand why it's insufficient.I'm pretty miserable,because I have no idea what to do next :(
And it's already the 3rd time,they want my picture,I made a new picture and the quality is great.

Thanks for helping!
