Bot keeps creating accounts, starting som hour after initial launch

Hi!

We launched our new login with Auth0 a couple of hours ago. I see a lot of users with the “same” gmail adress, adress leading to the same mail box at least. This is not eligible users, the account emails are verified by pressing the verification link, but they do not complete the registration at our web page.

Q1: Any idea what the offender is after?

Q2: Is this possible to block in Auth0, dots and ±addresses from generating different accounts for addresses that goes to the same mailbox?

Addresses looks like this:

ir.i.n.a20.2.0k.ob.zar2020@gmail.com
i.r.in.a.2020.k.obzar.2020@gmail.com
i.ri.n.a.2020.kobzar20.2.0@gmail.com
i.r.ina202.0k.ob.za.r2.02.0@gmail.com
i.rin.a202.0.kob.z.a.r.2.020@gmail.com
