If what is being said that the LBA management have been threatening posters on PPRuNe is true, be assured that your anonomity is safe. PPRuNe does not release details of anyone posting here.
If LBA have a problem perhaps they should address it instead of protesting that people who have the interests of the airport at heart are protesting!
Indeed, let them look here in PPRuNe. It is a hive of information about all aspects of aviation and if something is falling short in aviation it will. more than likely, appear here.
Don't let anyone tell you otherwise.
