1.I did try. Logged in xxx.yyy, but upper right corner still shows my account, which is xxxyyy
2. I didn't try because from the result of 1 above, I think if I already have xxxyyy, then no one can create a new account using xxx.yyy in the first place.
Nobody owns xxx.yyy@gmail.com
If anyone does, he/she can log in using his/her password, and I can log in that same account using my password, then the situation is so weird and I am totally lost.
Am I right?
