Facebook accounts are not collateral. They can be easily recovered using social engineering.
Then Twitter accounts should also not to be taken as collateral as they can also be recovered because both are social sites.
Please quote if you think i am wrong on the point.
I will be cautious in future while funding loans to the users with Twitter account as collateral.
Thanks
From personal experience, Twitter accounts aren't that easy to recover these days even if you contact support. Once the email attached to the account has been changed and you don't know or have access to the current email for password reset, support will tell you to contact your email provider for assistance and they won't do nothing about it.
