Thanks Tom. The fog had rolled back just past the boats, so everything behind them was blanketed.
I've begun to do a little research into the forum spam, and as I understand it, the posts themselves aren't the real reason for the spam. The idea is for the posts (and the spammer's profile) to contain as many links as possible to the spammer's site to increase that site's Google status. Google's rankings are calculated in part on the number of links that point to a particular site. Meanwhile, I feel like I've gotten quite a babysitting job!
