Nowadays Facebook become more strict in allowing people to have more than one facebook account. If they sense any suspicious login activity they will definitely lock your account and next time you login, you must verify photos tagged by your friends -The stupid photo tag verification. It is almost impossible to remember all the photos you are tagged in and the people who tagged you. So here is the method i use to solve this. Things i use : SCREEN CAPTURE EXTENSION for google chrome. What you have to do is to capture the screen that appears for each photo verification and saving it as image file. So next time when the same image appears, you can easily find the common person in both the images , i.e the person tagged in the photo. Facebook will give a chance to verify photo tag every one hour, and each time you will have a seven sets of photos to verify. Save those seven sets and next time it will be easy to find the right person.. Try this method only if you think the account is more valuable as it is more time consuming.
