You want to be in front of your competitors, thus you think
about writing a fictitious, negative review concerning them.
A negative review might see sort of a little act, however
realistically it will have an enormous impact its wrong!
Everyone is aware of the rule "do onto others as you
could have others do unto you".
Play the game fair!
You want to beat your competitors as a result of you have
got a far better business, not as a result of you probably did one thing to
harm them.
