According to the site, on August 26 (the day when the queues were longest), the number of requests for Pornhub, which featured the word Warcraft, increased by 210%. Then the popularity of thematic porn began to fall.
It is possible that some people just wanted to kill time watching porn videos while waiting for their turn in WoW Classic.
August 28, the number of requests decreased, but still it was higher by 120%, weeks before the release of WoW Classic.
We will remind, in July (during the flash mob “Storming Area 51”) has a similar situation, but then the users interested in Xhamster movie about aliens.
