I have about fifty websites, I get thousands of them every day, I don't even remember when it started, almost all of them are search URLs that say "sorry we didn't find any results".
That idiot Google accepts them all, when I tried to contact them they asked me for more information.
My sites are of various nature, galleries, videos, with only text, with content from affiliate programs, or from social networks like Twitter, Tumblr, Reddit (they send me DMCAs anyway).
I also get a lot of DMCA requests via email from alleged law firms, copyright companies, etc., I always remove everything, then onlyfans models, manvids, etc. contact me, pissed off with me because I removed their content from my sites and from Google.
DMCA is just a tool to destroy the competition, unfortunately the only idiot who still doesn't seem to understand it, and who doesn't care, is Google.
