I don't know what it is about this show that attracts foot fetishists. My theory is that they watch the show just to see Riley's sandals. Mind you, Riley is a middle schooler. A few months ago, I blocked someone who ran a cartoon foot wiki. Their English wasn't up to par, anyway.
Some people go beyond that. I just blocked someone who pesters voice actors on Twitter about seeing certain characters squished flat.
I can't believe I have to say this, but if you're a pedo, I will immediately block you. I don't want you anywhere near here.
