That's the Imgflip wiki, there was also a MSMG wiki at msmemergroup.fandom.com but it got closed around March 18th causing me to contact Crafteeboi (I forget his current username) who had previously made the Imgflip Wiki on March 12th. This led to the slow growth of the Imgflip Wiki which completely stagnated in growth on May 31st when the MSMG wiki got unclosed by Neko.
Around August 2024 however, the MSMG wiki got closed again, with Neko being told that the information in the wiki "wasn't popular enough".
