Niantic boosts spawn rates for the latest Community Day

Pokemon GO players have had a major complaint about more recent Community Day events in the game. Players felt that the featured Pokemon for these events were spawned in numbers that were just too small, making a big part of the day wasted.
It appears that Niantic has heard those complaints, and set out to change things with yesterday's Swinub Community Day. Swinub saw its spawn rate increased by 95%, meaning players had a much higher chance of changing the featured Pokemon.
