I just wanted to pop in and say the most controversial rule by far that I've seen dealbreak many guests or people who were creating characters is the one where I basically say no child Face Claims. People don't have an issue with the rule that all characters must be over 18 almost ever, but the Face Claims one has got a lot of discussions/etc. when I bring it up to guests.
It continues to be the biggest dealbreaker by far out of everything else. For me it's 100% worth it, but I just found it interesting that almost no other rules cause such an immediate exit.
honestly at that point i'd just play on a RL site lmao
i don't know half the characters i use as FCs and expecting me to know the ages of random anime girl, which could range from 12 to 12000 and not change at all in design, is too much. i don't hate the 18+ rule on RL sites because most RL FC directories don't post minors, and also they sort FCs by age ranges.
you can run ur site however u want, but sometimes i think at that point, why not just embrace RL
