These bots have been around for quite a few months. They are not attempting to insinuate themselves into our inner sanctum by pretending to be knowledgeable members. Think of them as “phishing” expeditions. Their only purpose is to get you to let down your guard and click on a malicious link so you end up “pwned.”
See a member name you don’t recognize? Just joined today? Something a bit off about the post? Likely a bot. As long as you don’t click on the link it posts (sometimes right away, sometimes after a few days) you should be fine.
