Do you still have or use your embarrassing childhood email ID?

Absolutely not - I have a very straight-laced firstname.lastname email address. And then I have a bunch of other random email addresses I use for doing stuff on the internet that I don’t want associated with my day to day email.

Unsurprisingly it gets too much spam to be useful.

I'm not sure why anyone born after 2000 would be free of having a poorly chosen email address as a youngster.

Nah, I don't use it at all. Its too vulnerable to spam attacks
