Could you share some more information? You can send me an email with a screenshot. My site not serving any ads, does not use any shading tactics, pure HTML and CSS website with just a minimum of JavaScript.
- Some kind of anti-annoyance filter for (for reCAPTCHA or something?) https://filters.adtidy.org/windows/filters/237.txt
- An anti-anti-adlock list: https://github.com/bogachenko/fuckfuckadblock/blob/master/fu...
- Something about some kind of Indian ISP (?) injecting code into domains: https://github.com/sudotman/indianadblock/
If one of these lists got picked up by an abuse filter somehow, that'd explain why search engines and malware filters would throw a fit about your site.
