We are making changes to how we do our dupe checks and automating a lot more of the tasks involved.  To ensure that no one is accidentally caught up in the filter, please update your email address if you are using one of those services that gives you a temporary 10 minute disposable email.

We will be doing a full scan of all existing emails, those that are are flagged as the disposable emails will have limited access until they can be updated with a valid email address.

" Can we assume that, even if we are using a "throw-away" email, if it's been used for multiple characters/hours that it won't search for this? "

As long as you can get mail from it, then its all good.  If you run multiple gmails, yahoos, hotmails, whatever, its all good.

Its more of the "search google for free disposable temporary email" that auto deletes after X minutes.

johnsspamgoeshere@google.com is fine

q38ah3rtas@h37ahdkaehr.ru used to make a one time email for a one time occasion that you no longer have the ability to receive mails is not :)

Aye, i don’t use this email for anything else besides this game and have since 2011. Do I need to use the one I use for work/school?

As long as you can still receive mail from it, you are good.

TLDR;

If you are unsure if you are using a disposable temporary email address, you arn't. It would be something you would have searched for specifically to use. :)
