Countless emails and almost a week later, I concluded that Blogger's tech help website might be little more than a rubber room for frustrated users to pound the walls where no one would hear them.
Then I remembered an old technology tool: the telephone. Although Blogger provides remarkably little information about their company online, I was able to determine that they've been acquired by Google, so I called Google up (650-253-0000). By pressing zero, you'll be connected to the operator. Google's staff has been well trained to direct everyone back to the online help desk. However, they did give me two leads that in the interests of community service, I pass on to you, my loyal friends who may at some point find yourself in the same boat.
- Google provided me with a special email address (email@example.com) and told me to put a specific keyword in the subject line (bongo). They told me that this would get me a faster reply from tech support. I imagine that they change the keyword and the special email address periodically, so I would call Google and ask for this information if you need it. [Update: I received a response to my Bongo email almost exactly 3 days after I sent it, and after my account was unfrozen, so I don't think this is what resulted in action on my account.]
- After explaining my situation to another staffer (to wit: help, I've been in lockdown for a week and no one in tech support has responded to any of my emails), she sent an email to tech support herself. I believe that this is what resulted in action on my account, so this is what I'd recommend asking for. But, try it all and hopefully something will work.
I can understand what Blogger is trying to do with the spambots, and it makes sense for them to be over-inclusive rather than under-inclusive, but they're going to lose users (and really piss people off) if they aren't able to get us real users back up and running more quickly.
