The best way to handle unwanted mail, is to Block the member that you do not want to communicate with.
The only way you can block someone, is if they send you an Email or an eCard. Otherwise there is no reason to preemptively block them and fill up your Blocked List.
When you are viewing a Mail or eCard they sent you, click on the " Block this Member" button in the right sidebar. at the bottom of the page.
The next time they try to write to you, they will get a message saying they have been blocked - so they will know you don’t appreciate what they have previously sent.
If the member has displayed bad manners or bad taste, the Block feature is the best solution. However, you should report anyone who you suspect of scam or illegal activity to: Report Abuse.
