Never understood why people use it seems to be too risky. You can end up sharing an account with someone associated with some unsavory activity and end up having to explain it. Plus many sites allow users to view their login and download activity logs which means your private information can leak that way. Sure VPNs and TORs can help mitigate some of that risk but BMN isn’t for opsec it’s for continence if you alread…
I only ever used it to access things that should not have been behind a user account in the first place. It was really just an opt out for the forced "sign up for our newsletter/spam to download our app" type paths. The only thing it'd really leak is that someone with a particular IP had used bugmenot... Which many would likely consider an advantage over going through creating an account and potentially getting spammed.
