Nah, it's a specific kind of bot that scrapes threads and composes facsimile posts that can tangentially look like they're kind of on topic, if you don't look too closely, and which plug an external site - usually either a gambling site, or a stock marked scam site, but occasionally other similar things.

There's been a little bit of a mild infection here, but it's not rampant - just report them when you see them and the mods are usually very quick to clean them up.
