I honestly believe that it has to deal with the influx of 'i'm depressed' or 'this person needs love / wub' public raffles where people will complain about whatever / someone that isn't them being sad.
Now I know why I didn't make public raffles before (rofl); at least you see none of that in the puzzles section.
And trust me, if it reaches that point where people will complain about these type of things in the puzzle raffles, I think I'll personally be done.
Or I could just avoid the above by entering none of them and continuing the Touhous, who knows
