1. Fwiw - I thank @emptywheel for noting my Twitter lockout (totally appreciated!) over on Twitter, and all the Twitter users who responded with suggestions on how to get around Twitter requirements for my phone number.
2. One of the primary suggestions was to setup a phone number via Google Voice. Unfortunately that also requires giving my real phone number to Google and I'm not willing to do that just like I'm not willing to give my phone number to Twitter. Both are an invasion of privacy. They are Personal Identifiable Information (PII) that I simply refuse to provide.
3. So at this stage, and unless Twitter Support relents by unlocking my Twitter account, which doesn't seem likely, it looks like I will no longer be on Twitter. Yes, miracles can happen, but with no human from Twitter support answering my emails, I'm not hopeful.
4. No news from Twitter Support on unlocking my LemonSlayer account on Twitter, so I caved and created a brand new Twitter account. It's located here: https://twitter.com/NonSenseiUS/with_replies

@LemonSlayer
I stopped logging into Twitter on New Year's Day. Haven't missed it one bit.
@darthstar Unfortunately (or not😊 😉 ), I'm still Twitter addicted.
