I contacted blockshopper.com requesting them to suppress my information from their company's public search results for privacy reasons. Reputable companies providing similar services honor such requests, but I received a reply from Scarlett Simpson (*******@blockshopper.com) denying my request. Based on other reviews here, it appears that blockshopper.com in fact is not a reputable company.
Tip for consumers: This is obviously not a reputable or trustworthy company. I would advise against any business dealings with this company.
