Building a fanbase group is difficult if you do it on your own. It will eat up your time that you could otherwise use for other purposes. You will spend money buying whatever tool is out there like you will spend when you buy facebook likes. So why tire yourself building one when you can buy it ready to use? This is more practical than building one on your own even with the use of tools assuming you can locate one. Without tools, building facebook fan group is a gigantic task aside from the fact that you will build for a long time. You cannot do it overnight, you have to gradually grow your group through your friends and acquaintances.
