User blog comment:Mikel6718/Mystery of the Vandal Solved! What Really Happened on the Wiki's "Black Friday"/@comment-34202220-20190720201421

How I would have preferred to have seen this play out, in Goosebumps fashion:

1. A stranger is secretly living in your attic and decides to terrorize you by messing up pages all over the Goosebumps Wiki.

2. A ghost is reeking revenge on your family for your grandfather humiliating him at a prom, killing him, and burying his corpse in your home. He begins with you by editing pages at the Goosebumps Wiki.

3. You have multiple personalities, and a dangerous one decides to assert dominance by editing pages at the Goosebumps Wiki.

Your story isn't as interesting as my plots above, so I doubt many people here care. You're fine, man. Carry on. Sorry about your sister though. I'm glad you have her under control. :)  I understand sibling rivalries. I have four brothers myself.
