Answer:
In the Fair play policy: it states "Do not open more than 2 accounts (a second anonymous account is allowed for training purposes").
Chess.com Support says every member can now have 2 accounts. In some cases, this can still be considered cheating.
I used the form, but what was strange was that I had to use a different email to be able to create the second account. If two were really allowed to be created I expected to do it all above board even on the same email, but I guess that isn't supported yet.
I'm pretty sure emails are going to remain as unique entries.
