Great idea, in concept, but provides little actual effect in practice.
For instance, I currently own 3 domain names (non are commercial, all are personal in nature) in which I could setup a limitless number of email accounts, also including a "catch all" so that they don't have to be monitored separately when waiting for the "confirmation email". Also, domain limiting can't be used, because then only one person on gmail, one person on AOL, one person on Hotmail, etc., could ever join.
It does, however, appear to me that
nearly everyone on this site is affiliated with an essay writing service. This, unfortunately, makes it extremely difficult to believe, or even attempt to believe, any post on this site. It seems impossible to truly know if any of these "services" are legit, or produce actual origin work, at all. You read one post, it sounds good, then someone else posts about how that poster is affiliated with site A and they are only trying to tarnish the reputation of site B, then poster A comes back and says the exact same dribble about poster B!
