I was interested in the Steam machine, but I might not get one because I cannot log in to my Steam account, for no reason that I know. Steam's web-based process for resetting my password always gets stuck after successful completion of the captcha, regardless of which device or OS I use to do it, the accessible-to-Google procedures for getting past that blockage have not worked, and the email address that one could once use in this situation now just sends an autoreply that says no one is monitoring it anymore.
So I have exhausted all of the obvious routes for logging into my Steam account. Perhaps there are additional routes to discover, but I'm not particularly motivated to look for them at this point. If just getting logged in is this painful, I'm not particularly optimistic about the experience of buying or owning the thing.
Steam Support can probably get it sorted.
Probably, if I could contact them. But all the links I turned up lead me back to the captcha black hole, and the only email address I've found elicits a reply telling me that nobody is reading it. Perhaps something is reachable through additional effort, but I'm not particularly motivated to keep searching further. Perhaps someone there reads HN and would like to know this happened to someone, in case they want to fix it (for someone else's benefit if not for mine).
