When you visit blockland.us, it doesn't look like the most advanced site out there. When I bought Blockland I actually had an idea in my head that it could have been a scam or that the purchasing method was buggy. Badspot should try and sign up Blockland for the BBB (Better Business Bureau). He can post the image that they give people on the site so that when new users think about buying the game, they will not have any second thoughts that this could be a scam and that Blockland truly is a really good game.
-CONCLUSION-
My main suggestion is for Badspot to add a counter of how many people have bought the game and who are still buying it and post it on the website, or to sign up Blockland for the BBB. (I have read their terms and regulations, Blockland would qualify)
