A good example is Ahmia.fi, once a reliable directory, now overrun with fake wikis that are almost impossible to distinguish from real ones. My approach here is different. I’ve created a communication channel for reporting and verifying both good and bad links. I listen to users who bring real evidence. I use many onion services myself, and I share my honest experiences here.
