Безопасен ли optout-mzkl.net?

I'm in the same trap , these websites start with " ***** " , you've never opt'ed in but your email was probably given to them without your permission , they'll spam you and there's no option to stop but to BLOCK them, do not submit your email in the optout , because that will only tell them you are a vaild target for spamming.

This web site offers fake opt-out / unsubscribe from the ColocateUSA spamming network. But without opting-in or subscribing, they send spam anyway. Submitting your email address to this site simply confirms to the spammers that your email address is valid. Don't do it.
