I'll tell you what I do.
I have an email account for my subscriptions.
One for my jokes and fun purposes.
One that's very private that only a few people have it.
Use an email account that has a good filter. I use Yahoo for subscriptions. I use Gmail for my fun. I also have a private Gmail account. I use the filters they provide. Yahoo has many that slip past the spam blocker. Gmail is pretty good.
NEVER post your email address in any forum. Don't let them know your email address is firstname.lastname@example.org or abuse @gmail.com The spambots will search the internet and find these email addresses and start spamming them. A good forum will have an email this user button or some type of private message system. If you have a business that you need to post an email address, make a special email address just for that. There is a way to code it if you need to know, just ask.
NEVER unsubscribe to these email addresses that are spam. Doing so just confirms that your email address is current and they will no longer send you emails. They will then send you emails from another email account and also give your email address to their friends.
People forward emails. Your email address travels and is shown to others. After it's forwarded a number of times, a spammer gets it and starts spamming you.
Never open an email from someone you don't know. It can have a virus or spyware. Some are coded with html that send a message to the sender that the email account is active. Some even look blank when they really are sending html coding to validate you email account is active.
These are just a few ways spammmers find out your email account is active.
I have read many threads here on this topic, but still have questions.
My ISP has a filtering capacity & filters about 99% of spam that comes to my address. It is put in a box call SPAM BOX. It is automatically cleared every 24hrs. I usually get 50-100 a day. I follow the instructions to highlight all & call them SPAM which means the sever filter is supposed to identify them as addresses I don't wish to recieve mail from again. I'm not sure if it works that well considering the number I get daily. They are all selling viagra, fake watches, men's enhancements, computer programs, etc.
So I decided to try to find the source & stop it myself. I started checking through the list of mail (without opening any) & was apaulled to find many originating from my email address or a similar address or from my name or a very similar name. I created a box that doesn't get automatically cleared & I put those emails into that box til I find out more.
I think I have found where they are eminating from. I once clicked on a diet site................?!!! I have tried unsubscribing, but that brings on a new wave of 100's per day. It's been 8-10mths now & it hasn't gone way by itself. I do what my ISP tells me re teaching the server filter what mail I don't want, but it still keeps coming.
Luckily I never have to let it load onto my computer. But it means I always have to log into to my server first & do all that stuff before I can open my OE (Outlook Express)to download my emails. Nothing I don't want get to my OE which is good but I can't leave it open or the next lot that lands in my ISP box might come in automatically.
How can I cause my email address to be unusefull to spammers?
