@jcbrand Did it twice. Once around circa 2012 when twitter was going to enforce personal detail collection (versus opt-in). Second around 2016 when I hit the threshold of what you described in OT.
@jcbrand yes, even blocked it in my dns so that I don't accidently log in with some client which still caches the profile, when I returned to it in 2013 I found it just restored my _deleted_ account.
