GuerrillaMail is down, appears to be so for the last 5 days (guerrillamail.com)

GuerrillaMail is one of the oldest no-fuss throwaway email providers (since 2006!). They have been threatened by different things over the years, it's a big loss to privacy if they shut down for good.

I like this alternate service: https://www.smartnator.com/

For the stupid services that require an email to signup

Looks up to me.
