rough number of posts per month for the Spam Months (nov 2017-sept 2018) (this is just posts minus topics, cuz 99% of the spambots made new topics to spam)
November 2017: 242 posts
December 2017: 460 posts
January 2018: 354 posts
February 2018: 428 posts
March 2018: 553 posts
April 2018: 516 posts
May 2018: 524 posts
June 2018: 334 posts
July 2018: 268 posts
August 2018: 140 posts
September 2018: 177 posts
this makes the current month the most active since August 2017, and it will (>99% chance) end up with the most posts since January 2017
