Thanks for emphasising that this is not the first time the guy and his circle have been conspicuous. The more you deal with the crap, the more ‘forgetful’ and insecure you become. Sad. I don't feel like spending my free time blacklisting either.
And why all this? Because there is no consequence. The only consequences are drawn by the good bloggers. They disappear without a word (just like Patjewell, right?). Very, very sad.
‘Positive pedagogy’ is great. But unfortunately, no social community (no state, no school, no... ) can manage without disciplinary measures. Unfortunately, that's utopia.

I heard a funny story on the radio today: In a small town, the police officers from the public order office (traffic) have stuck notes on parked cars. On every one! As usual, the parking offenders received a demand for payment, a fine. The notes on all the others read: ‘Thank you for obeying the traffic regulations and parking your car in an exemplary manner. Keep up the good work in the new year! We wish you a Merry Christmas and a Happy New Year!’... Happy people... ;-)

With this in mind: Merry Christmas and continued good co-operation... :-))
