The fact that you do not see it, does not mean it does not exist.
It’s not me that I have to say the name of the plugin copied but doume https://make.www.ads-software.com/plugins/2015/12/14/sock-puppetry-is-not-welcome/
I not me who has to investigate, but the team.
In the repository there are more than one copy, some cleverly, some brutally.
With this I have nothing to add, except that I will turn to a lawyer for assistance.
Every time I write a post on this forum, the moderators always give me wrong: 8 years that I work with WordPress, releasing my plugins, and no one has ever protected and appreciated my work.
Have a Good Day!
