experience with emailsz users
good, bad, or ugly?
On our business directory, we get a lot of users registering with a emailsz (dot) com address. Lately, e-mails sent to most of the addresses have started bouncing (mailbox full, e-mail doesn't exist, delivery failed after 10 attempts, etc.) several months after registration.

Does anyone else have experience with users using emailsz addresses? I hate to start blocking legit users. But I also hate continuing to allow bad users.
I had never heard of them as a service. DDG turns up nothing and a visit to the "site" where one might register (?) is (http: ) an under construction graphic. Maybe a short term venture that dried up? The DNS is shown as hosted at A2 Hosting, Inc in Michigan (US):

209.124.64.0/19
Sounds like a scam effort ... get domain, run email addresses though it, burn it, move on to the next. By the time they move on the rest of the world is a month or more catching up. 

These days I don't spend much time on email domains bouncing. Two bounce and I nuke 'em. Life is too short.
