The rule has a double standard as to why it is written so vaguely. First of all, I must admit there is no way I could come up with a rule that would cover everyone's morale; that's simply impossible. I do not have the knowledge of the morale of other countries or cultures, let alone I would come up with a way to synthesize them all into a single clause. The second reason why the rule is so vague is because anyone can understand what's immoral, and, for my fortune, there are some actions/words/thoughts that are considered immoral trough the world. For example, even if there is people who use ' nigger ' or ' nigga ' or any other form of abbreviation of the word with intentions to refer to a friend hilariously, they still know that the word CAN and IS used in derogatory forms. Which, latterly, would lead to them being cautious about using it.
I can't say I'm clean from immoral speech myself, in the sense I might have said something that could be considered derogatory (I haven't been reported for anything, not once, just to drop any possible attacks). However, I do know that from the PoV of someone who used a derogatory word in hopes to sound funny, being derogatory to a person or a group was nothing near the offender's intentions.
Getting onto the report acceptation/rejection. Someone was nice enough to type it down for me.
The simple fact why some offenders get away with being reported for Immoral speech is that, we can't be sure whether who's telling the truth. However, for cases in which we are presented proof that the offense was directed towards the player which made the report, we don't hesitate to act. I've told many of the people who've asked for my help to solve their cases, as well as the people who I have punished due to this type of cases: I am not here to judge whether people are really offended or not about what was said to them, only to apply the rules. In which case, Jewel, if you were to send me a screenshot in which it is clear someone told you "I like titties" and you would explain the cause why it offends you, then I wouldn't hesitate to punish the offender.
For those who speak general immoralities at the view of the community, I try to put my input to the offenders, without, of course, being too forward about it; fRO players do have their right of speech, regardless if they misuse it or not. Some of you might already know my famous phrases for when I try to stop people from continuing their immoral speech. Things such as:
"Keep it PG-13"
"Your mom would not be proud of what you just said"
"Every time you say [word] God kills a poring"
I hope this can all answer your questions regarding the issue. If not, feel free to post again.
