Spam
I can't imagine the mods like to chase down dozens of spam messages across many threads, first thing in the morning or whenever they log on. It's ridiculous this morning.
Other boards have a way to block new users from posting active links. This works well, they make a post, see that there is nothing clickable in it, try again, and then give up. Instead of posting the same thing over and over all over the board.
Maybe the mods could ask the tech people to implement this?
