From time to time (we've had two in the last two days) we get people joining the forum and asking members to fill in a survey or questionaire on some aspect of brewing. Often they claim to be students but we only have their word to say that they are. Normally we (the mod team) will remove the post and PM the person stating that data mining the forum isnt allowed without the express permission of the owner. I cant remember once when we've then heard back from the person, not even to acknowledge our PM. So my feeling is these surveys and questionaires aren't what they seem.
