As the notice says, it is not just to prevent spam, but also abuse. While the internet will always afford some level of anonymity, the more that people have to put their real name to something online, the more likely they are to think about what they are saying, and hopefully not attack others.
Now, there are two points about that that I would like to make. 1) Anyone who has high school friends that disagree on politics knows that just by having someone's real name attached to a message doesn't mean that all of their posts will be civil, but it's a start.
2) We also realize that there is a downside of this in our specific community. There are some individuals (including those that work in the industry) that enjoy posting on the board, because they can share their knowledge and opinions with similarly passionate people, without it impacting their real life friends, work, etc. We obviously hate for those people to lose the ability to post without fear of their online opinions having real-world implications. But, as I've said before today, we are trying to come up with the best resolution to an all-around difficult situation.
This is where we have arrived for now. Will it be where we land permanently? Honestly, I can't tell you. But, we are optimistic that it will help maintain a certain level of civility on the boards moving forward.
