The opposite of "influencer." A person who is paid by corporations to denigrate, rather than approbate, a service or a product of a competitor. A corporate saboteur.
In this time of high inflation, our outfluencer suggested we promote our product being cheaper than our competitors', even though it has 4 ozs. less content to it.
An Influencer who gets out before those influenced wind up holding the bag.
I lost my shirt to an Outfluencer who I figured knew his stuff about crypto, but who scammed me just the same.
An Influencer peddling a product or service who has gotten out of a scam while others are still being pulled into it.
I had invested in Bankman-Fried's crypto exchange before this Outfluencer took all my money for himself.
