Безопасен ли erepublic.com?

Subscribed to GovTech(.com) email newsletters through InformationWeek and/or Schneider Electric (possibly, though uncertain) because the IT dept. had been receiving postal subscriptions for quite some time; therefore I bypassed any research. Since subscription registration, I have been consistently spammed with additional phishing attempts via email message. These emails utilize the same or similar graphic to Amazon, Facebook and LinkedIn. Email messages generate/forward from domains with slight mispellings such as "amazomm.com" and the like, but similar enough to manipulate an end user into thinking it is legit if viewed quickly.
