f I understand the subject correctly, you receive demerits for words that are not normally insulting or vulgar. There is indeed what we call disguised language (example; sal/oupe, konare (asshole) and still many others the list is long.
There are words that are used and have a similar spelling that could be confusing, but as you said, moderation rectifies in 90% of cases.
All a long, very long series of words have been observed and listed and classified in their own language by the collaborators (knowing and mastering the language and its futilities) working on and for the Flyordie site for many years.
