I think that is a load of bunkum rubbish!!! Especially regarding aviation it is vitally important that pilots can post anonymously to air and get advice on their concerns!
They are unique in the sense that they have to have medicals to continue their work /livelihood and hence need places or sites to air their concerns knowing that is is not immediately put on a record.
I can understand that a poster needs to know the qualifications and have confidence in the what is being posted here.
Homonculus with his qualifications alongside is plenty and attaching a name is a needless exercise.
It is quite in order for the moderator to know the name attached to the qualifications but totally pointless having to display the posters name in a forum such as this.
