All I know is that EFL are employees while ESL are employers in the industry.
Well, technically this cannot be argued against because, as it stands, in some cases EFL speakers are employees for the essay paper industry, and there are, of course, ESL employers in this industry as well. :| Regardless, and for the sake of staying on topic, the comments made by pheelyks and WritersBeware still stand, as they addressed the overpriced, poor quality services offered by the companies in question, which
happen to coincide with the fact that they are run by ESL owners and have a ton of ESL writers working for them. The comments you quoted are not silly; there's nothing wrong with them. :P
