A trope that has appeared in many stories but you haven't gotten tired of yet?

For me it's the "receiving a picture someone took of me" that has appeared in "My dead girlfriend keeps messaging me", "My wife has been peeking at me", "My sugar daddy asks for weird favors", and to some extend "Penpal". It's a bit cheesy but it's also fun and it reminds me of the sort of creepypasta that I would read back in high school. And also with the right set up it can pay off really well, like in Penpal or the sugar daddy story.
