I am reminded of this funny scenario being used as a reason to improve one speaking confidence in a book; I can't remember precisely what the details were, such as what they were wearing, but the analogy is (hopefully) the same:
A person walks into the room selling his new business plan, dressed to the highest standards-- suit, tie, every strand of hair arranged perfectly-- but when the budding entrepreneur starts to speak, the quality of speech is juvenile (note this has nothing to do with how well you "know" English if you're learning English, only the way in which English is being used), or if not that, maybe there is no confidence or no enthusiasm in the pitch or language being transferred through body posture, etc.
Later, another entrepreneur walks in dressed in a summer beach t-shirt and sunglasses. But the delivery of the pitch is eloquent, professional and of the highest standard of English.
Not being the one who wrote the book, I cannot vouch nor make judgement on the conclusion, but the message is that a lot of presumptuous reaction, or maybe impressions, are stemmed from language. I would stay away from swear words in any case. But I think that it would be unfair to say that an "injustice" has been done, despite the fact that I (take my opinion with a grain of salt, no offence is at all intended,) am not 100% comfortable with some of the responses the original poster received.
The main reason the poster was banned was because of the fear that he was a 1d professional spammer. Whereas the others who posted in the thread were known not to be inciters, there was an unknown element to a new poster-- but the nail in the coffin was the warning about the original poster being known on chess forums, and not in a positive light. The moderators could only act according to the best interests of the whole, after the second personal attack.
I am in no position to judge what your (Darren Snow) true intentions were, but if they were innocent, please act accordingly. It's the heart that counts, isn't it? The urge of every human being to better themselves and reach for the blossoms of spring, looking from a broader perspective at the whole position before making a move-- the locally best moves are not always best globally. While I would usually not consider myself anywhere near qualified or righted to comments on situations like these, I think it is also my responsibility, at least partially, to give back to a community that has given me something of worth. And the attitude of the culture and training of pros and "any wannabe pro foreigner who finds himself here", as I think Mr Tourmanen once put it

, taught and reinforced for me respect, discipline, and to ALWAYS expect the strongest move from your opponent!
