Note this is Facebook Group Not Facebook Page
Benefits
A Facebook Group with followers will have more trust from Facebook than a regular Facebook Group. Using an Facebook Group with good Member/Followerd will be easier to develop and minimize the risk of getting banned when violating Facebook Policy.
Also, buying a Facebook Group with followers saves you more time than developing one from scratch because the followers attached to the account will be a good lever for a quick start and an excellent way to promote your brand’s popularity and credibility.
