I am not a spammer. You however seem to have appointed your self the judge jury and executioner. Unless I address and attack you personally I see no need for negative rep but that's just me. If it hasn't affected you personally then it's just censorship imho.
Repetition is not spam. Some folks require up to seven repititions to learn a concept. Don't take it personal, and I won't. but rep away at will you cannot silence me with negative rep.
I don't think I signed a contract that forces me to argue with anybody. I posted my opinion and if you didn't understand the meaning I am perfectly open to your asking me what I mean.
