All that above means we all need to have MULTIPLE back ups of our stuff, including at least an extra email or two or three accounts and for the extras, imo, do not use hyour hobby handle or info. And maybe even register those accounts from a different IP if they are on a hobby mail account.
I personally have had several secret yahoo, hotmail and other service accounts over the years kept totally apart from hobbying accounts and I try to use different IPs with TORs or VPNs or wi-fi's to both register and access rather than using the usual IPs from a hobby phone or laptop.
Yes, it is a chore to keep track, but I don't lose any sleep at night unless the "ginger" in bed with me insists! And that's how I choose some of my gingers!
