My bad, I thought it was server sided.
Except I don't post pictures of them in random topics, and walk around with hideous avatars that force people to look at them.
If I want to be exposed to a kiddies show I can always watch Playhouse Disney. You're just a freak.
I haven't seen people posting ponies in unrelated topics, and as for avatars you can either ignore them or use AdBlock. If you don't have AdBlock, well, I highly doubt it causes you physical pain to see a small icon of a cartoon pony, I haven't heard of that being a thing.
