Bismillah Al-Rehman Al-Raheem Assalam-Alaikum: I would only like to add one thing, if I may. If the intention of the writer is pure and blessed, the result will also Insha-Allah also be pure and blessed. I believe we have an internal compass to absorb any pure spiritual energy behind or surrounding the words on a subconscious level (even on the Internet). That is why, I believe, as much as possible to avoid fitna or misunderstanding, when we write, we should write for the sake of Allah, because that indescribable something in the people will avoid Insha-Allah the unsought result of what you have warned against herein. If I have said anything that is good and true, it is from Allah; and anything other than that is my mistake.
