Its called spam. Unfortunately most of us get way too much all the time. I think I delete about 100 messages a day - everything from unsolicited sales messages to women wanting to find romance (even with a picture do you even KNOW its a woman ?), to offers of money from closed accounts, lottery wins, offers of ATM cards from the Republic of Benin, Money from the US Federal Reserve, unclaimed packages at an airport, to … well you get the idea. The list goes on and so should you... there is a reason that each keyboard has a <DELETE> key built into it.
If you find that you are getting more than your fair share or are overly bombarded and have had enough, some of us have modified our keyboards and would make the following suggestion...
Enjoy !
