In a social or business setting, we all meet different people. Some are honest and very nice, a chosen few are rude and display behavior that would earn the chatter a lawsuit, In a "brick and mortar" business setting, it is not even legal.

What is inappropriate in the outside world, is also inappropriate in the internet marketing world. Ethics and etiquette  play a role in business of any kind, on or off line.

It is wrong to have a sexual conversation with a fellow employee. In my opinion, It is also wrong to have a sexual conversation in a business social network setting as well.

It is hard enough to gain credibility as an internet marketer without having to deal with rude, inappropriate people who are not here to learn and offer credible information.
