|(Someone on Ponychan)|
I'm not sure how 4chan's heirarchy runs, but moot was the one that fixed it last time, so moot is probably the one to contact this time. There was even a rumor of an actual /pony/ board in progress a while back, but that apparently poofed.
If you do get banned, and don't know anything about proxies/rotating IP addresses, you might as well hit up Ponychan(Tame) or Fimchan(Clop).
I'm sure it will all blow over again eventually anyway as 4chan mods get bored.
