Without any obvious warning on the Mailpile IRC channel itself, I have been kicked off Freenode with the message:
[error] Closing link: (~jack@[*** my Internet connection ***]) [You must use TLS/SSL and authenticate via SASL to connect to freenode please visit https://irc.com/login/sso in order to create an account. SASL Configuration: https://freenode.net/kb/answer/sasl - Webchat: https://webchat.freenode.net/]
I had noticed that the number of signed-in nicks had suddenly diminished over the last couple of days, so maybe others were kicked off before me.
Being generous, this may be an attempt to improve security, but if so it nevertheless indicates disregard on the part of the new owners of Freenode for the damage that this does to the #mailpile IRC community. How many people will never get around to ācreating an accountā? Couldnāt existing registered nicks have been grandfathered? This is good reason to switch #mailpile to another IRC provider.
