JLB,
As a French person, I am surprised that you wouldn't treat this web-site with the same respect that the French typically show when they shop or enter someone else's home. When I lived in France, I was acutely aware of the social customs inherent in the culture and adjusted my behavior accordingly. As a result, I had several years of great experiences over there, lasting friendships, and so on. Treat this web site with the same respect and I imagine your experience here will be similarly wonderful to my stays in France.
I understand that you might feel bitter about having your posts deleted without a due process but you have very few 'rights' here. It's a free forum, maintained by unpaid volunteers who are trying to keep a semblance of order despite a plethora of posts that come in every day. Moderators sift through this tsunami of information to cull cross-posts, offensive posts, etc. That's a pretty thankless job but it's essential to keep the site going.
Sit back for a moment and think about how cross-posting affects a site like this one, and I'm sure you'll agree that you shouldn't do it. Have a great day.
