Swearing is not allowed. The only vulgar words you may use are "hell", "damn", "crap", and "ass".
Why This Rule Exists:
We get visitors from every age in here, mostly because this oekaki is linked to Suta-Raito. Regardless of how you're raised, you have to consider the fact that it is ENTIRELY POSSIBLE that a 5 to 10 year old is not allowed to curse and thus will be upset if he/she sees it all over an oekaki, or their parents will be upset. Please do not complain about this rule.
