Why is Twitter stopped in many places?
Many people think of it as an invasion of privacy.
Twitter used to verify the celebrity accounts but that has stopped now but still there are a number celebrities on Twitter whose accounts are verified by Twitter. You should look for a verified symbol (check mark in blue). Number of followers can also tell you if the celebrity is real. Another important metrics is number of other celebrities that follow the celebrity. The celebrity page on Tweetwood would tell you how many celebrities follow him/her.
