It's one of their most reliable means of catching cheaters, so yeah. They do it on purpose. I recommend that every day between 4pm and 6pm EST, it's best to stop playing the game and periodically check things like the subreddit or one of the Discord servers. That's usually when these events start.
That's why you should give top priority to things like TLSQs. With cheats, you can bang out a whole quest in roughly 20 minutes if you're consistent about it and saving often.
