Not at all. There are some entries that are being altered/removed despite having been in the database correctly for quite some time.
Recently, I noticed a Lost Odyssey entry for the Xbox 360 was categorized as "NA" yet the title for the entry was changed to read "Lost Odyssey [CA]". The entry details still reads as if it is from the NA region.
I had to remove the entry I've had in my collection for about a year to whatever the newer one was, as I don't own Xbox games from that region. It's a little odd, though I remember there being a post awhile back stating the database had to be rolled back and some newly added entries may have gone missing.
There's also an entry for a gray game cube memory card in my collection that had its picture removed. Some Limited Run Games entries have also been removed due to water marks, though others games are still in the database with the same watermarks.
These are only some examples. You can always take a look at the style guide and the "Error Listings and rejected edits 2020" thread and point those out though.
Edit: As I posted this, I noticed the artwork for the blue and red memory cards I have in my PlayStation 2 accessory collection has also disappeared, haha!
