That's great. I'm very happy with the support and community on the Adafruit forums.
I had another thought that might help. I noticed on the account page that you request the forum username, so maybe it's also possible to determine human status by checking that record. I have an established purchase history with Adafruit with valid addresses, which hopefully differentiates me from the spammers.
I realize that's a lot to check on each post, but hopefully the more reliable parameters you have to check, the better the forum gets.
