Add-on works fine but it create multiple account threads by one specific user which means you're unable to find wheter member using multiple accounts or not after your Multiple Accounts section reach 10k+ threads all created by one specific member! Also it creates same thread every time user login with his alternate account so for example when member joined 100 times with his alternate account, then you've 100 threads for it in your Multiple Accounts section which is one of the worst part of this add-on.
