Recently, I have witnessed (and still am) a guy doing a giveaway at a said number of subscribers. Everything is good until you realize that his actual subscriber count is at least 100 less than the requirements in order to start the giveaway. He does hollas every 5 minutes or so in order to attract as many subscribers in an unethical way, forcing players to subscribe in order to receive a prize. Which means that the giveaway starts only once a goal has been accomplished. It reminds me of the payaways that had a tip piggy as a goal. Fill the piggy with the said amount of cubits and the owner will open it up for everyone. This case however does not involve paying cubits but subscribing to a random guy in order to make him open the gate and let everyone take a prize. And it's sad to see players subscribing to someone not because they like what the channel has but rather to get a prize in a giveaway... It just sounds so wrong to me.
I am all for giveaways that are hosted after a channel has hit a milestone, without advertising the said channel like the guy above does.
