Protect your email from spam for free - I just replied to someone on Site Jabber who was concrned about the use of their credit card and their cell phone number. My advice did not address their question, but I offered a suggestion on how in the future to be more cautious with your information.
The name "trashmail.net" may seem like something you'd probably stay away from but in fact its a wonderful alternative to giving your real email out to be spammed.
Trashmail.net offers a free service of disposable email to use wherever you need to fill out a form and suspect they will not use this honorably. If you try to sign up for online games, you need an email, and yes, they send you mail, but they sell your name. Thats just one example of how your email is misused by people you provide your email to.
Trashmail.net gives you free choice of a domain "trashmail.net" on the fly, and you just add whatever name you want in front of it and only they know where this email will be forwarded to (your real email). You advise them how long you want it, from one day to one month. Then, it automatically stops working after the requested date. Its easy to do,no forms to fill out, nothing to join, and you can do this by going to their web site or if you have Firefox browswer, you can add it to your tools and have it on your right mouse click ready to use on any form.
Finally, if you pay $2.00 per year, (they take paypal), you can use this service with unlimited time or specific time on the life of an email.
This won't stop your spam, but will certainly reduce it from being started by your providing it to the potential abuser.
