The strangest thing happened to me the other day. I got a handful of alerts from the playstore indicating users had given my app a poor review. I go to the playstore to respond to the users and the newly added reviews were gone.
About a week later, literally the same set of reviews are posted again by the same users. I look in my database and none of those names are present. Every day since then 3-5 of these 1-star reviews have been posted - and they are recycling the same set of false claims about my app.
After some detective work, I’ve found out who is behind this (In retrospect I should have known it would be this person/org since I already had a pretty strong suspicion that they paid for a sizable chunk of their reviews).
I have contacted Google and they are “looking into it” but I have my doubts about how successful I will be taking this route.
Does anyone here have experience dealing with such issues? If so what steps would you recommend I take to defend myself (that is - beyond writing a post on radar as a subtle thread to out the perp if they don’t call of their goons 
)
