This is a new service currently in pre-alpha to provide a useful tool for developers, communities, and gamers to build a following. With KG Pro, you will be able to create mass giveaways such as 500 or 1000 keys at once and require the user to follow on platforms like Steam Group, Twitter, and Twitch.
Along with mass giveaways, you will be able to do raffle style giveaways and require followership on the offered platforms just like the mass giveaway. Rolled winners will be auto-verified in case they follow/join just to enter the giveaway and then leave.
Why charge money? To support an influx of thousands of visitors to the website all at once, will require server upgrades. The cost is to address the necessary infrastructure overhead required to be able to handle the high volume. The prices below are not finalized and will more than likely change as hosting requirements are solidifed.
