I disagree. There's a finite definition of what constitutes pornography, but people always try to stretch it (in both directions).
davidmex/Loyal Teamster is a troll because he creates multiple usernames and interacts with them, often portraying different identities (e.g. long-time logistics manager, retired Preload manager, etc), for the purpose of knowingly causing a rise/disruption in the community. you aint even know it doesn't have ill intentions -- his threads are a reflection of his immaturity/inability to efficiently communicate his ideas.
OTOH, BrownCafe isn't always the most welcoming place. When I first joined, I was met with a barrage of negative reputation from people who merely disagreed with my ideas, as well as people who don't like the idea of PTers participating. Had it not been for texan, I wouldn't have continued to participate. Come hiring time for peak season, we'll once again see the dark side of BrownCafe, as more established members attempt to chase off the new members. Hmm... maybe those members will grow to be positive contributors -- you know, people who can write more than one post without blaming everything on ObamaCare? ("WWAAAHHHH... today I was dispatched yet again with 12-hours. Is it because I make $32+/hour with no-cost benefits, and UPS needs to squeeze productivity to turn a profit? Nahhh... it's that gosh-darn OBAMACARE!!") Ship gets old after awhile...
