I did a test about 3 months ago and hired someone in India to write 50 positive reviews on a random site. It only costed <$50 and the reviews are still here today. The statistics can be easily manipulated. Very poor review quality control, in my opinion. However, this review could be deleted soon since I'm exposing something quite fatal!
Firstly thank you for bringing this to our attention,
Our review platform expects and in most cases receives honest, genuine feedback. All reviews on Trustpilot are automatically monitored and we also frequently check domains manually. I can't say why the reviews you refer to were not picked up by our system, but if they have been posted under the circumstances you mention, I am sure that by doing a manual check it would be very obvious that they are not genuine - and would be removed immediately.
Please be advised that in addition to being a violation of our terms of service and an unethical practice, it’s also a violation of the law to post fake reviews in the United Kingdom, France, Italy, and Germany, Ireland, Sweden and the Netherlands (among other countries) pursuant to the EU Unfair Commercial Practices Directive, adopted by these countries.
