I personally knew of one somewhat hot headed Saab 340 FO who made a rather "unfortunate" post about a would be employer having just applied for his first jet job.
The fleet manager (SQ) read it, phoned up the individual within hours of the post........needless to say that was the end of that. He eventually ended up in the sandpit.
Junior birdmen need to be acutely aware that these forums are read by important people who may or may not post. BEWARE.
