Thank you everyone! WordPress came to rescue sometime last night and unflagged my site. I had already submitted a TOS ticket as thesacredpath suggested. The automated reply, which said they were closed until Monday, caused me to freak out and turn to the forum, but as it turns out, WP was able to respond quickly. I very much appreciate it. Thanks WP, and thank you everyone who responded here as well.
I do have a suggestion for WP that has come out of all of this. I am one of those users whose site is very important to them, but I do not necessarily even look at it daily. For instance, I've been very busy with a local journalistic project, so my byline has been appearing in print and online a lot over the last week. I had been assuming that people might be googling my name, finding my site, learning more about me, and perhaps even hiring me in the future as a result. However, despite that hope, I never actually visited my site myself this week until yesterday, when I saw it was done. I'm left not even knowing exactly how long the site was down for.
As a result, I think WP should perhaps do these things: (1) try to contact the user when their site is flagged BEFORE it is taken down, or at least generate an email to them that allows them to address the situation ASAP; (2) create some sort of blog verification process where you make people jump through a few extra hoops but then they are given the benefit of the doubt when the spam controls want to shut it down.
I am also left a little nervous that the automated spam controls will disapprove of me again as I do not know what on my site triggered the flagging.
But regardless, thank you for the fast response and action on the weekend. Very much appreciated.
