Just lots more common occurrences. When you've been here almost every day for Animal Crossing Bells a year, you get tired of visiting"[villager] spitting fire!" Because still another player is getting the"hating pineapple on pizza is trendy" conversation. And while it is mostly not a concern since winter is pretty much over, I got reeeeeal sick of seeing screenshots of misshapen snowboys stating"What. Is. Going. On." Yeah convinced that was funny the first 10 days it happened in early December. 

I spoil the bejeezus out of myself every time an upgrade drops and somebody goes in to datamine all of the newest assets even if they are still time-locked. I enjoy knowing what is coming so that I could best prepare for it. The one thing that disturbs me about time-traveling is when somebody posts about"eventually" achieving something that is simply possible through time-travel, such as getting all of the zodiac products, but we are pretty much past the point of being an issue now.

Memorials

These don't bother me at all, and that I can confidently say they are not submitted to make someone unhappy about death but to Buy Nook Miles Ticket recall and celebrate a loved one's lifestyle. When someone posts about a villager visiting their grandma's memorial, for instance, I just consider it as posting about the way they feel their grandmother is with them, and it is a happy thing.
