For the past week, I've received dozens, if not hundreds, of emails purporting to confirm my registration at one online forum or other. Each of them says I've signed up with a different username, and most of them give me the password. The emails are mostly identical enough that I've been able to filter most of them, but not the foreign language ones or the occasional one with different wording.
My first instinct was to suspect phishing, but I think that I've decided that it's spam. I've done Google searches on the forums, and sometimes that turns up nothing. I've only had the courage to visit one of those that does turn up (through the Google search, not the link in the email). The website for the Ocean Air Brokerage (I won't link for fear of viruses) looks legitimate enough, but the forums I've supposedly been given membership in make no sense. Why would the forums of a supposed shipping brokerage have no forums on shipping or customs or regions, but categories such as Sports, Software, and Phone Service? And every single post I've seen appears to be spam.
This leads me to the conclusion that these are spam forums. The only question is whether the spam forums themselves are sending out false registration emails, or whether some would be spammer is using my email address in his contact info. Either way, I have no idea what to do about it.
