I don't understand the phobia here. Spammers use all kinds of free email services. In all the years I have offered the email service, I have only heard of two such events.

Here is a few good samplings of email accounts that spam:
yahoo.com
comcast.net
netflash.net
boatus.com
geocities.com
cybermail.net
excite.com
gmail.com
googlemail.com
hotmail.com
linkshare.com
msn.com
netscape.net
prodigy.net
webdirect.net

Mary didn't seem to understand this entire thread. Just to go over it again, someone signed up for email to use the suffix of catsailor.com.
That allows them to send and receive email using that suffix. This has nothing to do with this Forum. People use free email all the time.., and most do not spam. Some do.
I know many emails I get have the Yahoo.com suffix. Also, I get a ton of spam (usually a few hundred a day.., due to my internet exposure) from Yahoo and all the others named above.
Most of those sites attempt to stop the spammers, but it has been pretty futile so far.
Same with our site, except I have had only two in our history.

As long as you are not the one getting spammed, what difference would it make to you what suffix a spammer is using? I should think none.

Just because this spammer (now deleted from free email) is using our suffix and email service, it does not get him any email addresses from anywhere on our site at all.., NONE, NADA!

Try it yourself. Register for the free email and just see how many email addresses you can glean from doing so. You will get NONE!
I hope this explains it better.

On Spam Mail, however, I hear a lot of folks really getting bent out of shape when they get a few. Best bet is to get a good mail program that sorts out the mail. I use Spam Killer in addition to what BellSouth.net and Verizon.com use. Pretty neat because I can choose the filters to kill by sender, suffix, name, country, or specific text in messages, i.e., in the body of their text, choose their URL, or phrases they seem to always use, the deliberate typos, etc.

Spam is here to stay.., we just have to find ways to put up with a little as possible.

Thanks for listening,
