The problem is that bugmenot themselves are preventing users from adding logins for specific sites Bugmenot to quickly bypass the login of web sites that require compulsory registration and/or the collection of personal/demographic information (such as the new york times). Therefore if there's a bugmenot clone that doesn't have this dumb policy, it would not have the same problem.
I tried to share the login of my geometry dash account that i cannot delete, on bugmenot Login details are here, if it matters I got this (error?) message
