Earlier this month, Mark Williams–a.k.a. “Mr. LinkedIn”–shared a post that’s worth reading if you’re a member of any LinkedIn Groups. Williams’ post, “The Great LinkedIn SWAM!” discusses the perils of site-wide auto moderation, which LinkedIn put into place earlier this year. In short, the policy, designed to penalize habitual spammers, has affected many innocent users. As Williams explains, “I have heard countless examples of professional, credible individuals who have never even considered spamming anyone getting hit by SWAM.” Read Williams’ post to learn more, but in the meantime, be extra careful with what you share via Groups–and in selecting which Groups to join in the first place.
