Google My Business has become a very competitive space, mainly due to being an organic channel...for now. There is added complexity with fake listings appearing in the map results. These results are designed to steal traffic from an established brand and to generate leads that can be monetised.
If you have a proactive strategy on optimising your listings and website then you should have an advantage over the competition. Fake listings just increase the competition, reporting them and having the listing removed will only help your own rankings.
