How can I avoid receiving spam on Usenet?

If you often leave a footprint on USENET, you may receive a lot of spam. Many spam Manufacturing Program Will automatically collect the email addresses in the news group and send a considerable number of spams. To solve this problem, you only need Article .
The most common method is to disguise your email address! You can add extra letters, numbers, and phrases to your email address. These letters, numbers, and phrases used to disguise the email address should be easily recognized by people, but they can be hard to recognize by spam manufacturers.
Of course, the method of disguising the email address will also bring about a disadvantage: after many years, you will probably forget the camouflage method you used before. Then you will go to the newsgroup to find your previous post, probably cannot be found.
The following describes how to mask an email address:
1) add additional letters, numbers, and phrases
Add some additional words to your email address to be deleted, such as "dontsendspam", "delete_these_letters", and "remove this phrase, or something like the following:
John.dontsendspam.smith@twenty.netjohn.smith.deletethis @ twenty.netjohn.why-the-extra-words.smith@twenty.net

in this way, the person who needs to send an email can determine the actual email address based on your email address. Of course, you should not use frequently-used blocking phrases like "removethis" or "nospam", because today's spam manufacturing programs are becoming smarter, it may even automatically recognize and remove these camouflage words.
2) modify the email address at will and provide auxiliary instructions for disguised email addresses.
A better camouflage Method, is to place a seemingly common email address to your sender column (which can be set in newsgroup reader), however, you need to add a real email address to your post before it expires or make necessary explanations. A better way is to write it to your automatically generated signature file. Below are some examples:
johncat.smith@twenty.net remove the feline from my address to get my real address.
john.tallsmith@twenty.net Delete the tall part to get a working address.
john.smith1750@twenty1850.net disappear the numbers to get from my actual address

a more professional approach is ". invalid is added after the mail address (which tells the mail server or a powerful mail client not to accept this mail address), such as a mail address like not@valid.invalid or your_favorite_fake_address@nowhere.invalid.
for information about how to set email addresses, each newsgroup reader has its own setting method. Please refer to the relevant manual.
3) Use a vest email address as the sender address
I believe everyone must have a vest email address dedicated to posting and publishing everywhere (what, you don't have it? Apply for one. Use this email address to send a post to a newsgroup, so you will not worry about it. However, there are several potential problems: first, you will inevitably receive a large number of spam; second, because there are too many spam mails, you may miss the contact email sent to you by the readers of the news group; 3. Your popularity in newsgroups disappears as your vest mailbox is discarded.
I recommend the second method in the above methods. By the way, when you want to send an email to someone in a newsgroup, do not send it as soon as one email is sent, check whether the email address in the post is disguised as described above. Otherwise, you will receive a lot of bounce messages!
