Parler CEO says he was fired by board

I’ve implemented email blocking recently where we stored a secure hash of the blocked email so we know we’ve seen it, but we don’t have it stored. So it is possible to do that correctly

Discord probably doesn’t do that though

Hashing is better than storing it in the clear, but many email addresses have too low entropy to make hashing an effective anonymization.

Someone did a pretty good analysis of that problem here: https://medium.com/@matthew.bajorek/using-hashcat-to-recover...

I ran such an attack on stackoverflow's data dump in 2011 and recovered about 28% of emails, using only a simple laptop CPU.

Somebody else ran a similar attack on a different dataset using a GPU and recovered around 45%.
