There is no link in that post as I see.
And here is a link to the profile of the person who made the post:
msitslolutionThe account has a link in his profile page at the website area and I see no problems with that.
You know accounts can even post about buying, selling Bitcointalk accounts in this forum. It's allowed but only discouraged and accounts with posts like that will be red tagged.
18. Having multiple accounts and account sales are allowed, but account sales are discouraged.
And that user is posting about buying accounts on other platforms like facebook, twitter, etc
Maybe, but the kind of service he is offering in that post doesn't exactly feel right, false positive reviews can lead to people wrong maybe even fraudulent apps, I usually go through reviews when ever I want to download a new app and if all of the reviews are praising the app then my best assumption is that the app is legit but when you are selling fake reviews then you are just deceiving people.
Also in this other post of his
https://bitcointalk.org/index.php?topic=5576412.msg66473447#msg66473447 he is offering to delete reviews so if a person had a bad experience with a product and makes a review on it the owner of the product can just pay him to delete it, he is basically selling lies and that can be dangerous depending on what he is lying about.
If what you are selling is legit then you have no reason to be afraid of reviews.
It can even be a scam service offer. There are some that are legit, they will do the work first, then the person will pay. I do not know what Google will do if they found out they are fake reviews, but this forum should not support something as deceitful as that. Such thread supposed to be taking down, either it is a scam or not a scam.
It definitely doesn't look to be very straightforward
