User blog comment:AzUrArInG/List of TowMatar's sockpuppets (including his original account)/@comment-30326002-20180401163900

Also for the Bowlingpinbox one, that account was made a few days before he made the TowMatar account, however slightly before he made the TowMatar account, he stopped using it until his TowMatar account and his DiamondFan518 account were both blocked, so he used the bowlingpinbox account after not using it for about a month (Feb-March) and he used until it was blocked.

Also, we know TowMatar and Bowlingpinbox are the same user because they both added Disney OCs, made rip-offs out of others, and much more.

So it's possible TowMatar forgot the password of his Bowlingpinbox account when it was first made slightly before he made his TowMatar account but then after his TowMatar and DiamondFan518 accounts were blocked, he probably remembered the password to the bowlingpinbox account.
