censored words: required reading

[El Diablo]

Ryan,

Another serious question. Which of the following are allowed:

[censored] you [f-u-k]
fuhck you
fk you
f you
fahk you
fek you
fuc you

Thanks. Alternatively, if you have an idea in your head as to what is acceptable/not, you could write that out. Just trying to get to a simple one-line answer of what is allowed/not when users ask.
