Spammers register here from time to time. We generally catch them within a couple of hours but not always. The penalty for spamming is immediate and permanent suspension in nearly all cases.
Any time any user sees thing s that concern them it is a good idea to send a note to a mod so it can be checked out. Spam is no exception, especially if it's of questionable content such as the one you noted.
Mods are always on the prowl for stuff like this and most of the time they are caught and eliminated before anyone actually sees them but once in a while they make it through the net. You guys have always been good at letting us know when they do. Together we can keep the website safe.
