College students have been cheating to complete their writing projects for generations; it's just that the most popular mechanisms have changed:

Thirty years ago, every fraternity on every college campus maintained a library of written assignments submitted previously, often cataloged by professor. Sometimes, those papers would be rewritten, updated, and changed as necessary to produce something that professors wouldn't recognize as ever having seen before; other times, they'd simply be retyped with a new cover page and submitted for credit as many times as the number of different professors in that course, or in that department.
Twenty years ago, companies began popping up online offering previously-written essays, providing many more options than the dozens of projects on every topic written by (and already submitted for credit by other) students at the same college and warehoused in fraternity libraries. Instead of being limited to projects already used at the same school for professors at the same school, students could choose from many thousands of projects written by students at hundreds of other colleges, nation-wide.
About 10 years ago, online originality-testing services began providing a means for professors to combat the student practice of submitting previously-written projects for credit. That mechanism, essentially, killed the entire business of selling pre-written college essays and promoted the explosion of essay companies providing newly-written original custom essays that couldn't be identified as unoriginal essays even when they were scanned by originality-testing systems. Unfortunately, because it's a totally unregulated industry, it also provided a ripe opportunity for any idiot who could pay for a slick-looking website to rip off unsuspecting customers, whether by taking their money and providing nothing in return or by hiring workers who just copy and paste unusable nonsense from whatever they can Google (and, often, right off Wikipedia) to satisfy the page count (but nothing else) of the order. For every legitimate domestic company, there are now dozens (or hundreds) of scam operations designed to mimic legitimate companies; usually, they originate and are operated from the same Third-World (and Second-World) nations that already earned well-deserved reputations for running scams targeting American consumers in all sorts of other industries, and long before they decided to jump on the scam-essay-writing bandwagon.
Nowadays, instead of retyping old papers themselves or buying prewritten papers online, college students have to spend that time doing some research, but not necessarily research of an
academic nature; instead it's research simply intended to identify legitimate and reliable sources of quality writing and to distinguish legitimate service providers to avoid getting ripped off by all of the scam companies (and scam "writers") in this industry. That's the main reason they read forums such as this one.
