Height of Technology and dumbness

Now this is dedicated to all the Computer science students ...3
We have to read a lot of reports in our trading job..and also We subscribe to a lot of trial subscriptions...Those guyz (or infact their IT personnel) say that they maintain a database..But know what these automated programs will send you a mail that you won't receive further reports..But if you subscribe to the same service from the same damn email address we should technically speaking not be getting the reports...But now I have tried this on 3 differents sites(pretty famous ones in their line of business) and ..guess what..they send you the reports...so enjoy yourself and just keep registering from the same email address..dont bother to create a new email address...
