Thank you for your patience everyone - much appreciated.
We have been cleaning up our data over the past days and as part of our new data policy, we are only allowing cities that are available in our sign up drop down. So, unfortunately, custom values won't be allowed anymore. However, the values you currently see on your profiles are not random; these are values that you specified at the time of registration.
Having said that, we're willing to make exceptions and will look into rectifying city entries for users who have posted on this thread. Thanks!
[update] As far as the 'days old' problem is concerned, the dev team is looking into it and will resolve issues asap. We have resolved such issues for a few members already so don't worry !
