"First off, what type of person looks at the posting times of other people and compares them."
He does.
He literally keeps track of all comments, memes, activity, and whatever else of me and a bunch of other memers. A massive collection of screenshots, dates, time, etc.
He's the first to know when a memer's account is gone, asking multiple people if they know where they went.
Look at CanaryInTheMine that he made his brilliant deduction about, see how many months ago was her last comment.
He'll ask memers why they deleted comments, memes, etc.
The little freak is a genuine stalker creep, total cringe on maximum overdrive.
Now if that isn't some serious hide-the-rabbits-and-nail-the-garlic-to-the-windows-and-doors-and-make-sure-the-restraining-order-is-up-to-date-as-you-go-into-bunker-lockdown-alert material, I don't know what is.
