whether legal or not, when they see the increase in orders, regulation will start occurring. it is just the american way.
when you post the info on the thread - hundreds of people see it, and now know the site, and possibly order from it.
whreas if you just email it to the one guy that asked for it, then that only increases the number of people going there by one - you then get a slower growth rate, and it looks less suspicious.
worst yet - when you link to it from here, and people click on it - the other site can track where people are coming from - so they will see that BB people are talking about it, meaning they have one more responsibility in the matter.
generally speaking - unless you are talking about gnc type supplements, email the person and don't post to the board.
and saying it has been done before doesn't mean it is right.
