How to report suspicious App fake reviews?

There is a dropshipping app that I’m looking to use that is free, however, I noticed over 200 reviews but they seem to be suspicious. The alleged reviewers have only used the app for less then 5 minutes and they’ve given the app 5 stars, also, their websites are defunct. Is there any way to have this app developer looked into? Thanks for the help.

There should always be a level of assuming positive intent, but if you strongly feel that reviews are fake or deceptive then do contact the support team.
