Type	Website	Platform	What is wrong	Checked
Real estate agent	`s*********.com`	WordPress	its domain publishes no SPF record, no DKIM key and no DMARC policy - Gmail has required SPF or DKIM from every sender since February 2024, so your own emails risk the spam folder, and nothing stops a stranger sending email as its domain the site runs WordPress 7.1, which WordPress.org's own version list marks 'insecure' - 3 newer 7.1.x releases have shipped since, with security fixes the site does not have the exact WordPress version is published in the page source (attackers search for sites by version)	2026-10-12
Dry cleaning	`b*****************.com`	custom / unknown	no working HTTPS - browsers mark the site 'Not secure' and search engines rank it lower no mobile viewport tag - the site renders as a shrunken desktop page on phones, where most local customers look the home page has no <title>, so the Google result shows the bare address	2026-10-12
Computer	`i********.com`	WordPress	HTTPS works but visitors who type the address land on the insecure http version 4 stylesheets and one script on the home page load over plain http on its https version - browsers block those, so once visitors are sent to https, whatever they provide (fonts, styling, a widget) is silently missing your phone number, (number), is plain text, not a tap-to-call link - iPhones guess at it, but on Android phones tapping it does nothing, so the caller has to copy it by hand, and many just call the next business instead	2026-10-12
Dance	`h************.com`	custom / unknown	no working HTTPS - browsers mark the site 'Not secure' and search engines rank it lower no mobile viewport tag - the site renders as a shrunken desktop page on phones, where most local customers look your phone number, (number), is plain text, not a tap-to-call link - iPhones guess at it, but on Android phones tapping it does nothing, so the caller has to copy it by hand, and many just call the next business instead	2026-10-12
Car repair	`h*************.com`	custom / unknown	no working HTTPS - browsers mark the site 'Not secure' and search engines rank it lower no mobile viewport tag - the site renders as a shrunken desktop page on phones, where most local customers look no meta description - Google writes its own snippet for you	2026-10-12

How it works

Email s.n.psaradellis@gmail.com or use a link above. Name the city, a business type if you want one, and where you will use the list.
Every row is re-checked before it ships, so a site fixed since 2026-10-12 is dropped, not sold.
No personal email addresses are sold, and any business that asked not to be contacted is removed.
Pay by card after you have seen the free rows. $49 for the urgent-defect pack, $149 to keep the city to yourself for 90 days.
