Activity Detection rule Flags users who check in many times over a period of days. This is aimed at preventing employees, as well as guests who live or work next to one of your stores, from checking in based on proximity without actually making a purchase. The path is:
Platform-->Settings-->Activity Detection Rules--<User has visits more than a threshold in last n days>
In this rule, you can enter the visit counts in accordance with the number of days. Find the screenshot below:
Once you set up the rules, you can see the "Suspicious Activity" on the user's timeline who has visited more than the set threshold.
