How to prevent/avoid fraud submitting/voting?
Hi Experts,
Do you have any idea on how to prevent or avoid the fraud submitting?
A "helpful" or "Not Helpful" buttons are tracked in our content pages.
If user clicks "HELPFUL", event1 will be fired, "Not Helpful" will fire event2 in "Other Click" type.

Recently, we've noticed plenty of fraud data in the report, more than 10K "Yes" to 1 document (e.g. ID:FAQ000001) per day, same document could get another 10K "No" in another day, from same IP.
But in fact, the "Vote" function has been disabled in front-end in that document (FAQ000001).
So, do you have any idea how this is happened and how to avoid this issue?
I asked to the Development team, they told me, if the events are fired and transfered to Adobe Server, the counts will be added.
SURE I understand this, but they also said they cannot control what send to Adobe Server.
So I am asking your help on this.
Thanks in advance.
