Does anyone use Fiverr gigs to combat poor ratings?

I hope I’m not breaking any rules here. I just wanted to know if anyone has used one of those fiverr gigs to boost their ratings. I got hit with a couple poor ratings and of course they windup being the ‘most helpful’ reviews.

This is the only gig that seems to have a lot on queue (I’m guessing it means its good?)

I’m just not sure if Google will bring down the ban hammer with reviews like this tho. Is it safe?

i used it twice. 15 five star ratings for 2 different apps and none of them got banned.

Thanks. I ordered one and it works great.

I usually have my friends review it. And if they like it, I ask them to give me a five star.

Isn’t risky to use fiver services to get reviews ?

Does the reviews really boost our downloads? I don’t think so.

My opinion is that if one has to choose between many different app/games that to almost the same, he/she will probably pick firt the one that has the better reviews / rating.

So, it works (not always) but it works.
