Hello, Google reviews is not solution for us. We'd not like to anyone be collecting reviews about us. It's not due to we are afraid of the score, which as I told, it's acceptable on Trustpilot. On-line reviews is something fake in total, and I see our nearest competition is buying reviews. We don't want to compete with something false, and from other side - we'd like to focus on maintaining our business, not discussion with frustrates.
What I did, and maybe this will help someone - try to collect reviews on your own website, and try to disavow in search console incoming links from sites like trustpilot.
You're right in that reviews online can be faked. But unfortunately you don't operate in a vacuum. If you don't have reviews on the main platforms your customers look on, or you allow a competitor to post fake reviews for you or them, then you have problem.
Google has well over 80% of the online searches and Trustpilot is the biggest player in UK reviews. Even if you succeeded in removing your business from Trustpilot, the only way to stop Google reviews is to not have a Google Business listing, this puts you at a significant disadvantage for local and branded searches. Especially if your competitors have great reviews on their profiles.
If customers are influenced by this in your industry, and all the research and data suggests they are in almost all markets, then the only way to win this battle is to proactively manage your own reviews. You can do without Trustpilot and build reviews on other independent platforms, plus show them all on your website, but unless you don't rely on internet searches, doing without Google is a different matter.
Disavowing inbound links from Trustpilot does nothing to stop them ranking for reviews about your brand, in fact all it does is weaken your inbound link profile and hurt your rankings. Unfortunately, you cant swim against the tide here, Google make the rules for how search works, and if your competitors are gaming the system you need to come up with a legitimate process that works better.
It sounds like you're trying to do this, but simply adding them to your own site wont cut it unless you rank way better then all your competitions. Even then, unless you are using an independent 3rd party review platform to generate reviews, you can't markup and show reviews in your organic search results.
