I am pretty sure that a guy that has a game """like""" my one it is voting negative and publishing bad comments on Google Play about my game on a daily basis, just to force my app to go down and get more profit in his one. I think he is using several gmail accounts for that and may be the emulator to fake several devices.
He contacts me by email the first days I publish my own application because I have commented on his one with my true and unique Google Play account a month BEFORE I published my game, and he excused the poorest quality of his work telling me that he was unemployed, and was not a proffesional programmier, that he did it its best and so on in a such pathetic way... I felt so sad by him that I decided to erase my own comments (well, I substituted the text by a '-', since I did not found a way to delete them on Google Play).
Since that, I have received several negative valorations without comments on my own game, and even a review so shameless that includes spam of his own game, that nobody likes except himself with his several fake accounts.
So, do you know is there is any way to handle such attacks?
Thanks a lot in advance,
