Sending of spam messages on websites and to email address has become the order of the day. It gets really annoying for me when I open my mails to see a lot of irrelevant messages from websites and people I didn't subscribe to. As a website moderator, it becomes a painful chore to scrutinize each message and comment being displayed on my website. Some people tend to use inappropriate words and drop irrelevant links that do not relate to what is being discussed most times and this could lead to their removal from the website.
Also, most times I get tired of filtering the number of irrelevant messages I receive in my email frequently. What I usually do is to select all and move them to Trash. I've found this to be time saving but notwithstanding it has not proven reliable all the time because I sometimes end up not seeing and deleting important messages that might have found their way to my spam-box in between.
