It's frustrating, but some of the product/service providers (Google, Facebook, YouTube, etc) have a "delete first, ask questions later" mentality. Many of the flagging protocols are completely automated, too, so it might not have even been a person that flagged your blogs (and I highly doubt it was anyone within the Appleseed community). One of the largest firearms YouTube channels, Hickock45, had his entire account shut down recently because of a mysterious terms of service violation. He eventually got everything reinstated, and found out that it was apparently an automated shut down over a minor issue that he didn't know about.
All that said, keep talking with Google; you'll probably get everything restored in time. Realize that they don't have tons of people to handle customer service issues, so it may take some time & a lot of persistence from you.
I would also suggest looking into moving your blogs away from Google, even if costs you a few dollars a month. Of course, also keep a backup of all your work in case it should disappear one day. That way you can recreate your blogs in a different space relatively easy. Sorry that you're going through this.
