Yep, an entirely valid point and the reason I called myself an idiot - I used my real name and my email and I stupidly assumed I'd have some immediate control over public visibility, or at worst, the ability to undo what I'd entered or nix the thing entirely.

Given the sign-up asks for both details and I assumed there might be some potential for further use here for a platform created by a trusted party, I unthinkingly stumbled with the minimum.

I usually - which is to say always - don't, but here did.

Not looking for sympathy or sanctimony, just relaying my experience.
