The last sentence of the abstract felt especially unnatural:
> since spread via social media is no longer restricted to specific locations such as local communities or school environments spread via social media is no longer restricted to specific locations such as schools or towns.
The whole sentence could use some more punctuation marks, like so:
A large number of young people across different countries are affected, with considerable impact on health care systems and society as a whole. Since spread via social media is no longer restricted to specific locations such as local communities or school environments, spread via social media is no longer restricted to specific locations such as schools or towns.
The second sentence both says the same thing twice and actually doesn't make any sense when you parse it.
> Since spread via social media is no longer restricted to specific locations such as local communities or school environments, spread via social media is no longer restricted to specific locations such as schools or towns.
The sequence "spread via social media is no longer restricted to specific locations" appears in exactly that sequence twice in that sentence. If you cut the redundancy down to "spread via social media is no longer restricted to specific locations", that doesn't make sense either since social media was never restricted to specific locations.
I'm not saying it's definitely written entirely by GPT, but mindlessly repeating sequences is very GPT-like behavior. Maybe academics are using GPT to pad their word count? Or maybe the authors and their editors just need more coffee?
They used the phrase "spread via social media" and pointed out that spread isn't locally restricted anymore twice for no reason. They're also using circular reasoning. A more concise way to phrase this would have been:
> since [the images and videos] are shared via social media, spread is no longer restricted to specific locations such as local communities or school environments.
> since spread via social media is no longer restricted to specific locations such as local communities or school environments spread via social media is no longer restricted to specific locations such as schools or towns.
