So was looking through a thread about learning maths and saw 2 posts that seem to advertise the essay selling services or at least plausibly slip them into the conversation. I'm guessing they chimed in because its talking about "education" even though the link between maths and essays isn't a natural one.
Check out these "peoples" post history. It's ad's for all kind of stuff from bitcoin to home services. It's cleverly done.
