We all know that spammers like to join this forum and post inappropriate advertisements. The moderators do their best to remove these posts as quickly as possible. Please don't reply to any of their messages, it just clutters the board and brings their message back to the top of the list.
There is an entirely different type of spam that is also beginning to clutter this board. There are several "trolls" that search to make useless or argument inducing comments. They start confusing threads and carry out cryptic conversations on the board. The best defense is to ignore these users. You can engage the ignore feature and hide all of these user's comments. Also, resist the urge to respond to their comments.
