What we checked, in full
20 checks, 15 passed, 2 to review
| ✓ | Metrics came from the platform | Every audience figure here is a value X's own API returned, never estimated or inferred. The price estimate is the one number we work out ourselves, and it is labelled and shows its arithmetic. | not published |
| ✓ | Enough recent posts to judge | 12 recent posts sampled (target 12). | not published |
| ✓ | Average impressions ≥ 20,000 | 141,504 average impressions, median 46,683, across 12 posts. | required |
| ✓ | Typical post also clears 20,000 | Median impressions 46,683 and outlier-trimmed mean 65,143 both clear the floor. A sponsored post should land in that range. | integrity |
| ✓ | Tech / dev / software engineering | 10 distinct dev signals in the bio and post text: rust, http, docker, coding, developer, engineer. | required |
| ✓ | Not a gaming channel | No gaming signal in the text. X publishes no content category, so this is a text judgement. | required |
| ✓ | Not a hardware / gear channel | No hardware/gear pattern. | preference |
| ! | Target region (US / UK / EU / AU / NZ / SG) | This creator's profiles disagree on where they are: X says Poland, YouTube says Czechia, GitHub says Poland. One of them is wrong, so neither is treated as settled. | required |
| ✓ | Like rate ≥ 0.15% of impressions | 1.52% like rate, 0.090% comment rate, averaged per post. | integrity |
| ! | Average is not one viral outlier (X limit 15×) | Top post is 22.1× the median (1,029,842 vs 46,683 impressions), against a typical X spread well below 15×. The average is carried by one hit. Budget against the median, roughly 46,683 impressions, not the headline average. | integrity |
| ✓ | Comment volume matches the view counts | Median 34 comments against 958 median likes: a normal ratio. | integrity |
| ✓ | impressions plausible for the followers count | 141,504 average impressions against 68,297 followers (207%). | integrity |
| ✓ | Posted recently | Last post 12 day(s) ago. | preference |
| ✓ | Publishes on a regular schedule | Median 1.4 day(s) between posts; the 12 sampled posts span 294 days. | preference |
| ✓ | Sampled posts are recent enough to compare | The 12 sampled posts span 294 days, close enough together that their impressions counts are comparable. | integrity |
| – | Same numbers from two endpoints of the same API | No post from this account appeared in both the search index and the profile feed, so there was nothing to cross-check. | not published |
| – | Verified against the platform's own published feed | X publishes no independent public feed to check the API's numbers against. YouTube is the only platform here where that second source exists. | not published |
| ✓ | An independent creator, not a company's own channel | Nothing marks this as a company-run channel: it is not a known company account, the name carries no corporate designation, and the bio is not written in a company's voice. | required |
| – | Same person confirmed on other platforms | No other public profile was linked from this account, so this record covers one platform only. | not published |
| ✓ | Runs paid promotions (platform-declared) | 1 of 20 recent videos carries YouTube's paid-promotion flag. | not published |
