[foaf-dev] FOAF OnlineEcommerceAccount

I just ran the following

SELECT DISTINCT * WHERE {
    ?product a <http://xmlns.com/foaf/0.1/OnlineEcommerceAccount>
}

With 4 results against sindice.

http://sparql.sindice.com/sparql?default-graph-uri=&query=SELECT+DISTINCT+*+WHERE+%7B+%0D%0A++++%3Fproduct+a+%3Chttp%3A%2F%2Fxmlns.com%2Ffoaf%2F0.1%2FOnlineEcommerceAccount%3E%0D%0A%7D&format=text%2Fhtml&debug=on

Would it be safe to say the OnlineEcommerceAccount is not used?

I'm thinking of a new use for it ...
