The Twitter thread has a lot more. There's a person or firm who is doing black-hat content marketing at scale. They either approach freelance bloggers to write articles about their clients (to be submitted to Medium-hosted and similar blogs as if written by unaffiliated users), or create Medium profiles for fake names and write the posts themselves. Posts have appeared in Better Programming, DEV.to, FAUN, freeCodeCamp, HackerNoon, ITNEXT, JS in Plain English, Level Up, Towards Data Science, and other aggregators. From there, they use dozens of fake Reddit and HN accounts to submit, comment on, and artificially boost their own posts. They also submit some unrelated cover posts. You can see some of these on HN here: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=by%3Aabjecton%20by%3Aargh-man%20by%3Acryptofits%20by%3Abreadandcrumbel%20by%3AEdward9%20by%3Aflywithdolp%20by%3AGeneloJ%20by%3Ahaybanusa%20by%3Ahyustan%20by%3Aiflywithbook%20by%3Ainvestologia%20by%3Aiunternik%20by%3AOwnsE%20by%3Aplastic_teeth%20by%3Apoticer%20by%3Aprescojan%20by%3Apresiozo%20by%3Aruffmill%20by%3Ashirak_untel%20by%3Athereyougo%20by%3Atruckster%20by%3Auinerimak%20by%3AWoodenKatana&sort=byDate&type=story https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... They have sockpuppet Reddit accounts doing the same thing across 10s of subreddits. Here's the set of clients I know of (https://twitter.com/troyd/status/1316020415995674624 https://twitter.com/troyd/status/1316020415995674624): AccessiBe ClimaCell Imperva Loadmill Rookout Labs WhiteSource (AKA SecureCoding dot com) Testcraft I have no idea what they thought they were buying, but what they were receiving was black-hat content marketing at large scale. There may be other clients I don't know of. Here's some Medium profiles of authors, where you'll see those companies get plugged over and over. I expect some of these will be removed by the authors soon: https://medium.com/@AntonLawrence https://medium.com/@AntonLawrence https://medium.com/@Justin_Parsons https://medium.com/@Justin_Parsons https://medium.com/@geeostan8 https://medium.com/@geeostan8 https://medium.com/@Dickson_Mwendia https://medium.com/@Dickson_Mwendia https://medium.com/@arinoman https://medium.com/@arinoman https://medium.com/@oyetoketoby80 https://medium.com/@oyetoketoby80 https://medium.com/@mrsaeeddev https://medium.com/@mrsaeeddev https://medium.com/@ginomessmer https://medium.com/@ginomessmer https://medium.com/@diptokmk47 https://medium.com/@diptokmk47 https://medium.com/@sajjadheydari74 https://medium.com/@sajjadheydari74 https://medium.com/@ngwaifoong92 https://medium.com/@ngwaifoong92 https://medium.com/@SeanHig https://medium.com/@SeanHig https://medium.com/@henson.casper https://medium.com/@henson.casper https://hackernoon.com/u/ari-noman https://hackernoon.com/u/ari-noman https://hackernoon.com/u/diptokmk47 https://hackernoon.com/u/diptokmk47 There's probably others I'm missing. If you run a blog and one of these companies is mentioned in a post that doesn't disclose an affiliation, it may well be fake. I contacted many of the publishers above.
