They are advising users to immmediately deactivate their Social Warfare plugin and immediately. Others like Casey Markee have advised switching from the Social Warfare plugin to another one. There are plenty of other WordPress plugins to choose from for your social media sharing needs.

Unfortunately, this is the last straw! I UNEQUIVOCALLY recommend that all Food, Lifestyle and DIY bloggers migrate over to Social Pug. They have a seamless migrator to move all settings & pins. DO IT NOW! https://t.co/R88sy4nfxK cc: @shellyfagin @TopHatArsen https://t.co/Ru2rNWbNZB
