There are some good guys who invented this, I don't know for what reason. But there are also some bad guys who are abusing this. So, who are those bad guys?

As you all know (or not) disposable email services offer you a solution to create a temporary email in order for you to register on some “not very trusted” services. When you receive the message on your disposable email address, the message usually gets redirected to your real email.

That's the catch here. There are way too many disposable email services on the web, and of all of them barely 5% work really well.

However, today it's hard to distinguish which sites are good and which are not. There are some sites, which, in my opinion, use this strategy to sell your email to spammers. You enter your email with the hope to save yourself against spam and at the end you actually get more spam! Think about it. Isn't this a very smart scheme to use?

So, what's the solution? My recommendation would be to use your real disposable email address on services like Google, Yahoo, MSN for registering on websites you don't absolutely trust.

Or you can try to review the credibility of the site. For example, check this article in PC Magazine.
