What Does TripAdvisor know about review authors?

New member here so please excuse if this is posted in the wrong section.

My question is, what does Tripadvisor know about the submitters of reviews?

My position.
Laptop connected wirelessly to netgear router, onto bt static ip landline. Using HMA paid for proxy software, and Ccleaner to remove all data after each and every browsing session/site.

Using multiple Tripadvisor accounts, with different emails addresses, different browsers, different ip addresses.
Using a mix of writing styles and authors, some with 1 review, most with multiple reviews. Done at random intervals weeks apart.

Now, these reviews have been flagged, Why?

When submiiting the review, what can be found out about the reviewer? I would imagine IP, Browser, Email Address..but if these are all different what else?

I am not a techie, but can the machine mac address be seen? I was led to believe that the proxy machines mac address would be seen, not my machine.

Are the HMA ip addresses known to TA and flagged?

Please Help.

I'm 100% sure it was the HMA IPs that got the reviews flagged. HMA is a very popular VPN client and therefore their IPs have already been burnt. You should look into buying private proxies for each account. Good ones will cost you about 1.4$ a pop.

Btw, wrong section. Ask a mod to move it.

Thank you so much for your reply.
May I ask how do you get a Mod to move it?

Thanks.
