To further muddy the waters, there are reputable writers like FreelanceWriter, who has a site but chooses to use an aol account.
Thank you, I appreciate that. I can easily un-muddy the waters in that respect by admitting that I'm just too cheap to invest in a more advanced website that supports contact. I'd probably spend that money just advertising more on here to direct people to it before developing a more advanced website. I use it strictly as an informational source for clients and simply provide my email contact on the page. It's explained in greater detail below.
Some of the very top writers in the business are on this site and are using email addresses of the type that Major mentioned.
In my opinion, it would be more accurate to say that there are
exceptions to most rules, and even more accurate to say that it doesn't follow from "All A are B" that "All B are A."
Crooks in myriad businesses obviously use those types of emails, mainly because they can be changed easily and an unlimited number of times; but that doesn't necessarily mean that there aren't also some legitimate users of those types of emails. I don't have a dog in that fight, since I've used the same 1 AOL email address for writing since 1999 or 2000.
When I created my intuit page in 2010, I added a second AOL email for the sole purpose of easily being able to know how many customers found me through that page based on which email they used to contact me, and I've never conducted any kind of business using any of those other types of emails listed. My first response to any email on my newer account always asks to switch immediately to my main email, so there's nothing "hidden" about that. I also have a 3rd email on a different ISP that I had to get when I worked for the government. More recently, I've used that email only for business purposes on behalf of my co-op building Board of Directors as VP. Nothing hidden about any of that, either.
I suggested that most of them (not all).
One could easily flip that to say the exact same thing about the "hidden reason" that some large essay companies would invest so much more money than that to create many different user-end websites, all with totally different company "DBA" names and not even the slightest hint to customers that the same company actually owns and operates all those very different-looking websites, typically relying on the exact same group of writers and customer-service and administrative personnel regardless of which company takes the order. So, to be fair, there are probably some crooked essay companies and freelance writers who maintain or create multiple sites and/or emails for "hidden" reasons and some totally legitimate essay companies and freelance writers who may both use multiple sites and/or emails for equally legitimate reasons.
