Giveaways are fake growth, those people that followed you twitch or Instagram, will only care about the giveaways, they will not watch your twitch streams, and will leave when their is no money.  The only thing Andrew can gain is to show his social media numbers to sponsors, and advertisers, and say look we are big and have a lot of traffic so sponsor or advertise with us.  But those business that fall for this will see no return on their investment because all those followers dont care about e-sports just free money.
