Yes, you are correct. While fake reviews (and review farms) were still a problem behind the scenes, anyone doing incentivized reviews prominently told the buyer that the review might be sus.
Amazon got complaints about the number of people with the disclosure text in their reviews and so they banned incentivized reviewing. At some point I would go visit products and it would be 9/10 reviews with the disclosure text.
But banning it just moved underground, made it harder to tell who was doing incentivized reviews.
I'm doing a
budget action cam showdown series, and since buying these cameras 6 / 8 of the brands have been banned from Amazon. Not that I'd directly want to earn affiliate revenue off of selling garbo cameras anyways, but affiliate revenue is the primary way I make money off of my channel, so now I'm kinda screwed for breaking even on this series... Also I am kicking myself for not starting patreon 2 or 3 years ago, but frankly I am not a very interesting personality so I have struggled to build up subscribers on YT anyways. Maybe Patreon by now would have grown into an actual revenue stream instead of something I just post on and hope for the best.
For me I am happy if the hobby pays for itself, as much as I would like to go full time at video production, it has been at times like yelling into the void, so I have taken whatever I can get from sellers and done a couple things I'm not proud of in order to get free samples for the channel. At least everything I've written is my honest opinion, built through a decent amount of testing, though.
