I just found this gist of common temp email address providers and it crashed chrome when I pasted it into the textarea, probably as it was tokenized. It is a bit overkill to add them all in the UI so I wondered if it would be better to have it as an option.
As in true/false - “blacklist common temporary email domains” - and link to the list.
I can’t comment about the performance of this but as this is only for sign-up it should be pretty low overhead?
I’ve attached the list of domains (pipe delimited) for your reference.
