You “May Not” immediately cancel a trial offer or software download.
Advertisers will consider it fraud if you do not make a reasonable attempt to try their product or service. They are, after all, paying you to try their product or service for "x" number of days.
Advertisers require you to make an honest effort to try their product and to consider purchasing it. As a standing rule regarding trials, you should only sign up for a trial offer that you have a genuine interest in.
Canceling a trial immediately will result in a chargeback of your account and can lead to your account being deleted.
It is your responsibility to review all the terms of a trial offer, including the last day you can cancel a trial without penalty.
In addition, if you download software, including toolbars, the immediate uninstall of the software is unacceptable. This could result in a charge back of your account.
