Wait, but the title is specifically "isaimini+2015". So maybe I should focus on the timeline, like how isaimini came into existence after the takedown of isaimini in 2015. Or perhaps "isaimini+2015" is the name of the site after the original was shut down. Need to confirm the history. Let me think. Original isaimini was shut down in 2015, and then the site moved to a new domain, which might be "isaimini+2015". So the essay can discuss the problem of piracy resurfacing after takedowns and the challenges in stopping such sites.
