Posting to all your Facebook groups is a good way to Market and Promote
your Brand or Company on Facebook. This is a free,easy, simple way to do
it without spending hours selecting each group at once ..
Im sorry but posting two posts is not spamming i could understand you calling it spam if i posted it on the site like 20 times but that is just not the case and doing a short survey is way better then having to pay for a program
