I think it would be better to send them to your own as then you will be left with an asset that you can use to communicate with the members when ever you want, the more you do that however the more likely it is to get closed down.
With all the Phi**ing and crap like that going on, people are scared to click on spam links on walls etc, don't get me wrong they still click but the numbers will be less.
If you find yourself a good method of posting that you can automate then it could make a few sales but spam is something you always have to do, if you had a page you could invite a ton of people to it and then leave it for a month and do the same thing again.
