I was about to denounce Sloan and Grove for replying to spam, but thought I'm going to give them the benefit of the doubt. Who knows, maybe this guy just really likes to inform others about free-to-play games.
So let's look at his history. I see Solace773 has two types of posts.
The first type is much like this one; a paragraph about a free-to-play online game that, while not exactly hyping the product, is too positive to be considered unbiased. Suggestive of spamming.
The second type of posts Solace773 makes are much more overt. He's asked for permission to send unsolicited PMs to forum members in one thread, and has suggested the forum incorporate a system to openly link email accounts to forum accounts in another. They reek intensely of spamming.
I'll let you draw your own conclusions.
