In response to the recently-announced changes that PokerStars plans to implement on Jan. 1, 2016, the poker community has begun to organize movement for a strike to take place Dec. 1-3, 2015.
According to a post on the TwoPlusTwo forums, a thread on the Russian Gipsyteam forums was created to announce plans for a strike. TwoPlusTwo poster I from Russian wrote that the Russian thread spawned 130 participants within the first 24 hours.
Thanks to the additional momentum gained from the TwoPlusTwo thread and the mobilizing efforts of Dani "Antsy" Stern, that number of planned participants has since grown to well over 1,000.
