Anyone got SPAMs from webnamesolution.com? How they got a list of my domain names?

[Varchar]

I have been ignoring emails from this comany so called webnamesolution.com. I didn't paid much attention to their junk emails until recently. I realize that there tactic is to offer people to purchase the .com version of the domains which the recipient owns the non-dotcom version of the domain. I have tried to contact them, but they never wrote back. The reason I start to concern a little is because I am wondering how they get a list of my domain names? They have sent me many names that I own the non-dotcom version which I registered using enom and registerfly. Does that mean that both of these registrars were hacked?

I did check whois of many names and none of them are owned by this company.

I want to know if this is a legitimate company doing legal business. If not, how should I come about giving them a warning and ensure that they don't spam me anymore?

Thx.

They are spamming scammers. They do not own the domains listed on their site. Their hosting company doesn't care. They're Canada based, so not sure how to stop them. Do NOT give them money.
