How this score works
The score estimates how strongly this place's review record matches known manipulation patterns, from 0 (no signs) to 100. Verdicts: Clean below 40, Suspicious from 40, Likely Manipulated from 70. It rises with the share of reviews flagged and how suspicious each one is.
- Burst
- — an abnormal spike of five-star reviews in a single day compared to the place's usual pace.
- Low activity account
- — the reviewer has almost no other reviews, photos, or Local Guide history; throwaway accounts look like this.
- Duplicate text
- — the wording is nearly identical to another review of the same place.
Verdicts are statistical estimates based on public review patterns, not accusations.

In-N-Out is back! New parking layout is much less chaotic.

In & Out is back in business! The new layout looks nice. It was pretty busy for a weeknight. There were a lot of cars lined up and packed cars in the parking lot. Luckily, the lines were not as long inside, probably because people don't know they're open yet. I got the double double, animal style...
