Hey RM community - in the spirit of full transparency, I've decided to make a public announcement...
It's been a wild adventure since launching the site 2016, however I've decided it's time for me to move on. I'm now searching for a successor to ReviewMeta. The main concern is making sure the site will stay true to its roots - helping provide transparency to an industry that's increasingly darkening.
If you know anyone who would be interested in taking over this project, let me know here. You can also read more about why I've decided to move on and what's next for me.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
