If a post looks like that AND its source is Instant Messenger, there's about a 100% chance its spam - already reported.
Some spammers are a bit more clever, somehow posting as a normal user but the giveaway is usually that they have a very low to zero rating or even a negative rating.
I just report them when I see them and let cfnisbet make the final decision. We all have to do our part to keep this forum spam free.
If you see something that you're suspicious about, report it. Thankfully it doesn't happen too often but somehow this stuff seems to happen in bursts - several over a couple days then nothing for a week or two then... Go figure.
