On the XYZ website they say they have zero tolerance for spam. They're proud that they're hard-asses compared to the rest of the industry.
I have an email deliverability book. It says:
"To stimulate growth, one-year registrations of many of these TLDs, such as .xyz are given away by domain registrars for free or for a nominal fee. This results in them being resold and used by spammers."
I guess it's worth the effort to try to find a .com name that is meaningful but not taken yet.
