Mondo, let tell you about Haris18 himself and his sockpuppets.
Around 2015, Haris18 made his 1st account and he had his main goal, to vandalize the wikia. However, his goal was failed because of the wikia admins blocked him anyway and made the rule of blockades as "Haris18 is worse than Fegelein".
Few years later, in 2016 and 2017, Haris18 still did the same as his previous sockpuppets, blocked again and returned again to vandalize wikia.
As in 2018, we've been encountered the same guy with different sockpuppets. This guy has made all of the wikia member annoyed by his return and the trusty admins blocked him again to prevent him vandalize the wikia by swearing and ruining all of the page's contents. Now, the trusty admins make a Quick Tool to block him whenever he returns again.
So, that's Haris18's situation nowadays.
