I received an email from spamtrackers.eu regarding a few domains claimed to be spamvertised domains. They want me to suspend the domains. I want to know if spamtrackers.eu is trustworthy and I should suspend the domains.

never heard of it
spamtrackers.eu seems registered since 2007, it may be legitimate, but i would ask for proof before suspending any domain

So, can I wait for some more time till some other entity tells me about the domains, probably the registry or ICANN or the registrar?

I have been receiving continuous emails from these guys for various domains. Can anybody advise what should I do?

+1 couldn't agree more

Don't ever suspend your domains because someone asked you to do it.
Always ask for proof if you are doubting the site's legitimacy.

We get pestered by this bunch on a daily basis, there email states they are not requesting the domains to be canceled due to SPAM but for other reasons, therefore, unless it is illegal or spam related tbh we don't take a lot of notice.

Spam Policing!!!:uzi:

Some domain called spamtrackers.eu give me a break.
Started 2007 yep and what are they doing telling you to suspend domains without proof?

Always ask for proof, any way who are they? Well the domain suggests they helping you and I to crack down on spam.

I wouldn't respond to anyone, except the authorities of the country where my server is located, or my ISP.
